Hey,
I have a custom post type with an archive page and via the menu I link to the main entries of the connected custom taxonomy.
within the filter I can click + to see the sub entries. On the page “Bühne”: https://ck-veranstaltungstechnik.starts.design/technik_kategorien/buehne/ I can click on “Bühnenpodeste” to see this sub entries. But on Tontechnik: https://ck-veranstaltungstechnik.starts.design/technik_kategorien/tontechnik/ I dont see the subentries of Tontechnik, only the sub-sub entries.
Here a overview from the taxonomy terms: Tontechnik: https://prnt.sc/26cfrzl Bühne: https://prnt.sc/26cfs8e
Could you help me with that?
Link to the page: https://ck-veranstaltungstechnik.starts.design/technik/Hi Resi1402.
Sorry for the late response. I have COVID-19 these days and I’m not able to answer fast.
It seems the reason is that you have empty category “Beschallungsanlagen” and you activated option “Hide empty terms” and that’s why it was excluded from filter terms list. It looks like a bug in the plugin but as fast solution you can try to attach any post to the category “Beschallungsanlagen” and it should appear on the Tontechnik page.
Let me know.
Hey,
thanks for your reply. I hope you get well soon 
I tried your suggestion but it does not worked. On the archive page https://ck-veranstaltungstechnik.starts.design/technik_kategorien/tontechnik/ I still only see two of five terms.
I also tried to apply all sub posts to the parent term (Beschallungsanlagen). Thats also does not work.
Very, very strange, because we have the same issue on “Bühne” (https://ck-veranstaltungstechnik.starts.design/technik_kategorien/buehne/ ) and here it works perfectly.
Hope you can help me 
Resi1402
Really strange thing. I can check it more deeply if you send me credentials to your /wp-admin via PM. And before that install please Updraft plus plugin and creade a DB backup and also install plese Query Monitor plugin so I can check the problem rapidly.
Thank you. Let me know.
Hi, will send you a pm today. Thanks!
Hi Resi1402.
Thank you for your credentials. As I see your question is related with the Free version of the plugin and due to the rules it should be asked on WordPress.org forum. But as you already purchased license I will answer you here:
- this bug is alread solved for the next version of the plugin and update will be available on this or maybe on next week.
I checked this new version on your site and it works fine. Please, see examples
Hey Stepasyuk,
thanks for your response. Yes for this site we don’t need a premium license, so thanks for support
!
Okay, sounds great! So I will wait for the new version, 1.5.2 right?
Best regards
Yes, sure. Just update the plugin when the new version will be available. I recommend you to check you notification settings here on CodeCanyon and enable messages about new versions of the items you purchased here. Or you can install Envato WordPress plugin that allows you to update items in one click and gives you notifications about updates – https://www.envato.com/lp/market-plugin/
Hey Support Team 
I purchased Filter Everything yesterday and now I have a problem on displaying on my site:
- I’m using the Divi Theme and build the Layouts with the Divi Theme Builder. - I created a new Filterset for Woocommerce Products and set “Where to filter” on the Shop page. - Then on the Theme Builder Layout for the Shop Page I inserted the shortcode [fe_widget]
But the filter is not displayed on the shop page. What am I doing wrong?
Thanks and best regards
Hello selv90.
Thank you for purchasing the plugin. Try please to play with “Where to filter?” value and select Homepage, All archive pages for this post type etc. This should help you.
Hello Stepasyuk
Thanks for your suggestion. I set the where to filter value to: “Common pages” and “All archive pages for this Post Type”
But the filter is still not showing. Any other suggestions?
Okay, send me please credentials to your /wp-admin I will check it myself. You can send them via PM if you click on my username.
Sent you all the details. Thank you. 
Ok, thank you for your credentials. I’ve checked this and realized that you had to make Filter Sets translatable in WPML to be able to specify individual Filter Sets for every language. And also for some reason Divi makes regular Shop page as Single page and when I changed “Where to filter?” from Shop page to Page -> Videothek it became to work.
Try it please and let me know if it works for you.
Thank you. Now it’s working as expected.
Wish you a beautiful day. 
Best regards Salvatore
Super, I’m glad. Thank you for your wishes.
How does this work with Jet Engine listings? There is no documentation on this
Hello philsafc.
Thank you for purchasing the plugin. There is no need to create documentation for Jet Enginel listings or for listings created with any other page builder as Filter Everything works with them in common way.
Just select in the Filter Set options desired page, where you need to filter and, what is more important, select correct WP_Query in the field “What to filter?” If you are not sure what is correct WP_Query try please different queries until you find correct. And also do not use AJAX when you are configuring filter, please enable it in the end of all adjustments.
I have an issue with the range “view in widget” option. I am using an ACF field for the meta key, and the ACF field only accepts a number value. So the range option should work, but right now it is greyed out and cannot be selected.
Hello davidlindercodes.
Usually it is greyed because there are no terms in Custom Field you provided. Write please here in comments what exaclty meta key you used in the filter?
Hi, This plugin is not working with accents characters. If a taxonomy term name/slug contains accents characters the request url is returning 404. An example filter url is below. Example Url: http://example.com/shop/wl_composer-mr-%C3%A4del/ We wrote the problem in detail via an email to you. You can find details with some related files in that email.
Thanks
DevHelpers
Hi develhelpers.
Thank you for your report. I will fix this issue on this or maybe on next week and will release new version of the plugin.
Hi, Any update on this? Have you prepared new version to relase already ?
Hi develhelpers.
Unfortunately it is not ready yet. Last two weeks I was ill with COVID-19 so all my plans
Sorry to hear that you got COVID-19, Hope you are well now. Is there any update for this issue ?
Hi develhelpers.
Thank you for your care. I’m really feel fine for the moment and succesfully overcome Covid-19
About your request with diacritical marks. I investigated the problem deeply and realized that you have to store your term slugs in DB in URL encoded and in lowercase format. It is common standard for WordPress and for example all slugs for taxonomy terms always are lowercase in DB.
I can not add support for both variants uppercase mr-%C3%A4del and lowercase mr-%c3%a4del (in fact it can be even mixed mr-%c3%A4del or mr-%C3%a4del) because this generates too many variants of the same term with different slugs with different registers.
You example works fine if its slug stored as lowercase in DB, please see example – https://dev.filtereverything.pro/loc-mr-%C3%A4del/
So I recommend you to update all URL encoded slugs in your DB and make them lowercase. And also to modify your function sanitize_title_to_allow_accents(); so it always returns lowecase strings.
Thanks for your investigation. We will test the way you suggested, and will let you know the result.
Hi, It is working now. We did not change anything in our code. You suggested storing term slug in url_encoded and lowercase format, actually WP core function does that automatically. The problem was in a different place. We were using this plugin version 1.2.3. Our described issue was happening with version 1.2.3. Today we installed the latest version 1.5.1. And it is working as expected. We did get a chance to compare the code between versions 1.2.3 and 1.5.1. If we installed this new version before we would not have to face this hassle. We were not aware of the new version. We should have checked this plugin page for new version info. Could you make your plugin automatically notifiable and updateable from WP dashboard?
Thanks DevHelpers
Hi develhelpers.
Super! I’m glad that your problem is already solved. You should receive Envato notifications about updaes of the items you bought. As option you can check your profile settings to make sure you received notifications.
Btw, today I released new v 1.6.0 with new features and fixes.
Hello! I think i got the plugin up and running with Oxygen and woocommerce product filtering thanks to enabling the widget area again with another plugin.
however, i have a small random dot appearing at the top above all my filtering options. It looks lika a black “•”. I cant seem to get rid of it.
Hello therealrasmus.
I checked the link you provided in email, but it seems you deactivated the plugin. I can check this tomorrow in 09:00 by London time if you activate the plugin in this time.
In general it is a CSS issue and usually it’s not too complex to fix it. Let me know.
Hello therealrasmus
Sorry for the late reaply, I was feeling bad in last days. Now all is right.
About your issue. It is something specific for your Oxygen configuration or CSS. But you can try to fix this if you add next CSS on your site:
.widget_wpc_filters_widget::marker{
display: none;
}
You can add it in in Filters -> Settings -> Experimental -> Custom CSS. Let me know if it was helpful for you.
Hello Stoasyuk! Happy to hear you feel better 
Sorry to inform the snippet did not resolve the issue.
Do you have any other ideas?
All the best, Rasmus
Okay, let’s try this CSS that should kill it 
.widget_wpc_filters_widget::marker {
content: "";
}
It sure did! Thank you alot.
Another question, how to I add the possibility to add a range for sizes, for example. I want to use between the values of 1-6. Taxanomies? Attributes? Tags?
Ok, super. I’m glad it works for you.
Range filter is available for Custom Field Num filters only. I have plans to add range filters for taxonomies (tags and attributes are taxonomies also) in next updates, but I think it will be done in several months.
Thanks for rapid response. I’m having some issues with the product image+text getting squeezed when the filtered products are less than 2. See attached screenshot in email.
Do you have any ideas on how to resolve? Using Oxygen product list for woocommerce.
All the best, Rasmus
therealrasmus
I checked your site and filtered products so there was only single of them. And as I see now it works fine. Or maybe it works bad on other pages, different from the /katalog page.
If this problem appears only when AJAX is enabled it may happen if you specified incorrect value for the “CSS ID or Class of Posts Container” option. Try please to specify it in accordance with this article – https://filtereverything.pro/resources/plugin-settings/#ajax
If the problem appears independently from AJAX status it means that you have some CSS issues on your site. In general Filter Everything should not affect on your products grid.
Hi, how can I use website.com/ as url of my search ? I have seen on your demo is like that
Hi manzullo.
Thank you for purchasing the Filter Everyrhing PRO.
I’m not sure I understood your request clearly. Can you please send me link to the demo page, where you saw it? And explain please what is your goal.
Thank you.
As you can see the filter works on the home page. Is it possible to do it ?
A-a-a. Do you mean to specify Home page as page for the Filter Set?
Of course you can do it. Try please to select in the field “Where to filter?” value “Common pages” and “Homepage” or “Shop page” if you have your shop on the Homapage.
Hi, I installed the pro plugin recently, but I’m having some difficulties setting up a filter.
When I try to filter posts by category, the categories appear on the defined page but no results appear. I don’t know if it’s a fault in the plugin configuration or the fact that my theme doesn’t have widgets. Hope you can help, thanks in advance
Hi LEADSPOT
Thank you for purchasing the plugin. Send me please link to the page with the problem (optionally via PM) I will check it and let you know.
I sent a private message, thanks
LEADSPOT
Thank you for your example, I checked it.
First of all – please do not enable AJAX until you ensure that filtering works at all, otherwise you will not know where is the problem – in AJAX config or in filtering config. So please disable AJAX.
As I see it seems you have to select correct WP_Query that should be filtered. Try please to select other WP_Query in the field “And what to filter?” in the Filter Set and try to check if it works.
I disabled ajax, but in wp_query it doesn’t let me select another option besides post query
Okay, thank you for the info.
Let me know what posts your tried to filter? Grid of vine bottles above the filter?
And to make things faster, send me please credentials to your /wp-admin via PM. I will check it myself from the dashboard.
I want to filter blog articles about wine bottles
I already sent the credentials
Hi do you have any update? since i send you the credential the site stop working becouse of the folloing error
Your PHP installation appears to be missing the MySQL extension which is required by WordPress.
Hi LEADSPOT.
Thank you for your credentials. I didn’t check them yet. But just tried and I see the same error. You have to ask your hosting support to help you. It seems there is problem with your server software.
Let me know, when this issue will be solved and I will check Filter Everything config.
this issue is solved, you can check now
Hi LEADSPOT.
I checked your site and as I see filtering works fine. I’ve sent you link via email to the example wifth 1 filtered vine bottle. I attached it to the category “Branco” to make sure that all works fine.
Hi, thanks for the help, it works as expected
Hi, following on from this incase you didn’t get my last message: https://codecanyon.net/comments/27741132... I also sent you a PM. Thanks so much.
Hi brael.
We had Christmas holidays here in Ukraine, so I’m sorry that I didn’t respnod you before. But I already did it.
hello, do I need to keep free version installed and how to update pro version thank you.
Hello inscriber.
Thank you for purchasing the plugin.
No, you don’t need and you can remove the Free version. But for any case create please DB backup before removing it.
Hi there, I have installed your plugin in my site. I want to use this plugin with elementor. But When I go to edit the page by elementor then I couldn’t found the filter everything’s elementor widget.. see- https://prnt.sc/26b5pzb . Already I have done the filter setup.
I think, you give me a solution.
Thank you.
Hello sj_pavel
Thank you for using Filter Everything.
If you question is related with Free version of the plugin, you have to write it on https://wordpress.org/support/plugin/filter-everything/ But if your qestion is related with PRO versoin, you have to write it from CodeCanyon account, where you purchased it.
Thank you for your understanding.
Hi Stepasyuk, a few questions before purchasing your plugin. Is it compatible with the Woodmart theme? Is there a list of Plugins with which there may be incompatibilities? It being understood that we use very few plugins, of which those concerning the Shop are only Woo Discount Rules, Nexy Pay and the plugin for the shop on Facebook.. And lastly but more important to proceed, is it possible to test the Plugin in a subdomain before installing it on the main domain? Thank you. And congratulations on the plugin!
Hi gianluk74
Thank you for your congratulations and your interest in Filter Everything PRO.
1. Yes, the plugin was tested and is compatible with the Woodmart theme.
2. Yes, Filter Everything is compatible with plugins you mentioned.
3. Yes, you can use it for testing on subdomain before installing on production server.
So, you have all three “Yes” and you can go to the next round 
How can i use Filter term name hooks for url ? I have acf fields and in url i have field id in order to have field name. I use Filter term name hook to show the name on the page, but how can i do that for url prefix?
example of url now domain.com/products/risk-554/domain-612/
Example of url i neeed to have domain.com/products/risk-today/domain-check/
Url prefix is already set to: risk and domain
acf id = acf name 554 = today 612 = check
Thanks
Hello saveas
It’s a good question. Filter term name hooks are related with term names that are visible in Filters widget only. For URL parts Filter Everything uses term slugs.
In case of Taxonomy terms they are regular Tax term slugs, in case of Custom Field terms they are meta field values sanitized with WP functions sanitize_title(); to make them compatible with URLs.
So if you need to use slugs ‘today’ and ‘check’ you have to change values in appropriate meta fields. And to reset cached values you have to update any post/product/filter set or other post type on your site.
This posts are connected using acf Post Object field. When enetring a single post it shows the post slug as it should, but when using the filter, the slug is the post id and not the slug. In my example : /risk-554/domain-612/ (554 and 612 are post id’s) /risk-today/domain-check/ (today and check is the slug of that posts.)
There is any function to use so i can tell the filter to use post slug instead of post id in url? Thank you
A, ok. I understood what is your goal.
In general there is no such special function to handle term slugs for Custom Field filters (But it is good idea to add it in the future). But you can use ‘sanitize_title’ WordPress hook and to check if the value is “554” to replace it with it’s post slug.
But you may use it on your own risk as it may generate conflicts if you will have a title with the same value on your site.
Hi Stepasyuk,
Quick question: Is there any function to use to have the first (or any other) filter active by default/on page load. Using radio buttons if that makes any difference. I guess I could make it work by pointing site URL -> filtered URL, (using filters on the index page), but this would be somewhat questionable SEO practice. Any tips, ideas? Much appreciated, plugin keeps getting better and better. Cheers.
Hi millend.
Thank you for your warm words about the plugin (you can optionally say them in reviews)
Yes, you are right that you can use URL-predefined filter value to make it active by default.
From the technical point of view you can write some PHP code that will allow you to achive the same without additional path in URL. But I think it’s bad idea because it may generate conflicts and problems with the rest part of the filter’s logic.
Hi Stepasyuk, is the pro version compatible with themify ultra and pods? – Just tried out the free version – it can see and count the values and occurrencies of custom fields declared with pods – but when i try to filter the loop of posts inside a cpt doesnt get filtered. Does the pro version handle this more reliable?
Hello dukeEllington
Thank you for your interest in Filter Everything PRO.
Yes, it is compatible with Themify but with some specific settings related to the Themify architecture. For example AJAX feature works for site visitors but for logged in administrators it may not work.
Also it requires separate Filter Sets for Shop page, for product category pages (one common Set for all categories), for tag pages etc.
And also it is was tested and compatible with Pods.
I don’t know if it is a bit demanding? could you have a short look at the page in question and tell me if the issue I’m facing could be solved by the pro version? – Is there an option here to send a private message? Cheers, theduke
Ok, sure. Send me please link via PM (click on my username and you will see the form) I will check it in 24 hours and let you know.
dukeEllington
I checked your site and I have to say that PRO version can filter your posts-services. But with Themify AJAX feature will work properly only for ordinary visitors (but not for logged in administrator) and it seems in the moment after you will remove HTTP Authorizatoin. I’m not sure AJAX will work properly with this authorization.
Hi Stepasyuk, indeed the filtering is now working – in the pro version its importnat to set the correct WP query “And what to filter?” and of course – like you mentioned, you dont have to be logged in! in order that the filtering does work.
THX for a great plugin !!!
Super, I’m glad that it works for you
And thank you for your warm words about it.
You can also write them in plugin reviews 
not Showing on my shop Custom link
Hello , the problem is my shop link is not original Shop link
“xxx.com/shop”
now i was change my woo shop link to “xxx.com/newlink
when i go to ” Edit Filter Set – Where to filter? – Common Pages – Shop Page “
not working ! so any way can solve this ? thx
Hello ko531736
I would be glad to help you, but unfortunately support period you purchased is exceeded and you have to pay for it if you need my help.
Thank you for understanding.
sorry i don’t need , i was remove , because plugin totally not support WPML and also many problem ..
Strange thing.
Because the plugin supports WPML and why you did not ask about support before? )
You already tried to left 1-star review 7 month ago and it was removed by moderator. Now you again did it. It also will be removed because it violates the rules. So I recommend you to remove it by yourself because it is not professionally from your side.
yeah , i have no time to test it , because first time i install this plugin i can’t setup this well, than i just leave and remove , now i have time to testing on my website,
I recommend you to update the plugin to the latest version 1.5.1 and try it. It should be available for you here on CodeCanyon. But your 6 months support period included in price you paid is expired so it’s normal on CodeCanyon to paid for it if you need it. If you don’t need suppiort it’s also ok.
But please do not aim to force author to provide support via 1-star reviews as it violates the rules and should be removed – https://help.market.envato.com/hc/en-us/articles/207651633-Rating-or-Review-Removal-Policy-
Thank you for your understanding.
Even Free plugin author will help , but you tell me not support , well this not worth 40 $ even game Diablo 2 just cost 35 $ have welling game experience.
SO many Fake Rating
Okay, BinChun. I just asked moderator to remove your review as it violates the rules. Sorry, but your behavior is not professional.
Hello ko531736
You left me bad review in the third time. Your site may be broken because it was updated automatically to WP6.0 and you should update Filter Everything to the latest v 1.6.5 which is compatible with this WP version.
Bit I have suggestion for you – you can create a refund request from your account and I will return you money. If my plugin does not meet your expectations it would be better to stop using it.
Hi, I have 2 questions 1- how can I put a variable that putting the count of list or product in title or description
2- in this page https://realestateegy.com/list/type-chalets/city-north-coast/ I created a new SEO rule containing SEO content but when I open the page the content didn’t appear in the front end and h1 hasn’t changed SEO rule: https://prnt.sc/264zagr
thanks
Note that this page was built using Elementor
?????????????
Hi MAhmed145017
1. You have to code this moment and you can use function flrt_selected_filter_chips( $include_reset = false ) to get count of posts filtered. Here is more about API functions https://filtereverything.pro/resources/functions/
But I think you have to ask a developer to help you. Or just wait some time, I will add this feature in several weeks in next plugin update.
2. I will check this problem in 24 hours from laptop, for the moment I have smartphone only and I apologize for this.
thanks for your reply, take your time, i`m waiting
MAhmed145017
I checked that page and as I see the SEO Rule works and <title> meta robots and description were changed in accordance with the Rule.
/**
* @param string $key possible values are title|description|h1|text
* @return string|false Needed seo data
*/
flrt_get_seo_data( $key = 'title' );
This function returns desired data if a page contains it.
I know this is inconvenient for the moment and requires extra coding, but support such SEO data for custom created pages with page builders is complex thing and I had no time for this before. But of course I will improve this in future updates.
BTW, you have to use one plugin copy per one public site. Otherwise it will not work properly in the future.
As for using the plugin on more than one site, I tried it on a different site because I faced a problem and in the end I will use it on the main site and you can check this and you will only find the plugin on one public site
about the function, where i can put this function to get the data?
Thanks, i changed the archive page desgin and it work now
Super, I’m glad that it works now.
I have bought your filter plugin. But the filters won’t save. Some did like the first 50, but the others did not.
Hello StijnScheper.
It seems you have conflict with other plugins or something like that. Can you please send me credentials to your /wp-admin via PM I will check this?
StijnScheper
Thank you for credentials, I confirm I got them. Let me please know what exactly filter you tried to add but you got error? And what was the error?
In the filter set where you are now I wanted to add a filter, but it wouldn’t save them.
Thank you, I understand this. I mean what exacty filter criteria you tried to add (category, taxonomy, custom meta field)?
A product filter. If that is what you mean. So any criteria with product in the name.
StijnScheper
I checked this and there is no any errors from the plugin side in this case. Your server responses with status code 400 that means that “Bad request” was sent. In this case neither WordPress nor plugin loads, but server just says “Your request is bad”.
I’m not sure why it happenes and I think hosting support can give you answer on this question.
As option you can try to create additional Filter Set, add inside it desired additional filters and point it (the Set) to the same page and add second Filters Widget on the page. So when both widgets will be close each other it will look like a single filtering system.
A possible reason may also be a specific filter that you tried to add. If you remember the last filter you added and the system worked, you can try removing it and adding others. Perhaps the reason is in a particular filter.
At the moment, you cannot even update what you have already added in the Set. But you somehow managed to add it earlier. Apparently something has changed on the server since that moment.
It does not look the server Is the issue. When indeed entering a new filter set it works again. But that is not what I want. When in the first filter set making a new filter it should just work right?
And it is not saving and it is not giving any eroor code’s when I do it.
StijnScheper
Yes, sure, I understand your logic but in technical aspect when you tries to save your Filter Set with 57 filters (what is extremely too much) your server doesn’t load neigher WordPress nor any plugin nor Filter Everything plugin. Before this stage it just says “Bad request” and shutdown all. I can not even to investigate what is the problem in my code because it doesn’t load in this case at all.
It can happened for example when your server has limit of ‘post_max_size’ PHP setting that is less than request data size you tried to send when saves your Filter Set. And this can be changed only by web server administrator.
The previous plugin that I used didn’t mind the amount of filters that I used. So that is why I found it weird that this is not working. My server developer can check monday if the problem is really on his site. I hoped to have it fixed today.
I think the fastest way is to ask hosting support about that. They can check web server logs and this can help to find possible reason of the problem and ways to fix it.
Keep me posting about that.
Hi, I had to raise my servers “max_input_vars” Normally plugins slice the input on the variables. But yours doesn’t. Why doesn’t your plugin slice the capacity? Now when I save it it save’s all filters, also the one’s that are already added.
Hi StijnScheper
Thank you for your report. I’m glad that now it works for you. I did not sliced input vars because until you asked there was no need to do that. It’s very rarely happened case, when user creates more than 50 filters. In fact you are the first, who faced this problem.
But I will add this task to my todo list and do it when is the turn. And also I will notify you here in this comments thread.
Let me please know what is your current value of the “max_input_vars” that allows you to use more than 50 filters in a Set?
Dear Respected Author,

pre sale question. Is it full compatible with flatsome Theme? does this filter plugin show results instantly or it is slow?
Hello PetranRHO
Thank you for your interest in Filter Everything PRO. Yes, it was tested and compatible with the Flatsome theme. And also it works as fast as possible if your server has enough resources for products count on your site. You may not worry if products count is less than 20K. If more you have to use more powerful server than usually.
thanks for your reply, i will test the free version first. I would also like to ask you about the filter permalinks. Now i have disalow them from robots txt. I saw your demo page that permalinks make too much folders. I have in mind SEO friendly permalinks. thanks and sorry about my bad english 
No problems. Your English is perfect!
By default all filtering pages have noindex value for the meta robots tag. So you may not worry about SEO for them. If you need to make some filtering result pages available for indexing you can create SEO Rule for them in the plugin options.
thanks a lot
