Hello ThemeNcode please answer me about my inquiry of pdf viewer security

1) The pdf can be downloaded by Internet download manger when the viewer render the pdf

2) user can copy the content of the pdf and paste it in any 3rd party app like word

3) pdf url of the pdf viewer can be shared by member who have access to that pdf

4) url from pdf viewer must have session timeout

5) make the cache of the pdf viewer more secure

Hi, PDF Viewer for WordPress currently doesn’t provide security options to make your pdf secure.

We may release an addon for security soon but can’t confirm any timeline.


at least protect it from internet download manger because stilll blocking pdf from rendering check this screenshot

I bought your plugin but I can not use these features: - Enable/Disable social sharing - Enable/Disable Print Option - Enable/Disable Download Option

All the time the download and print button appear. What can I do? Also your ticketing system is not working…

Regards, Cristian

Hi Cristian, Please send an email to with your website url (where I can reproduce the issue).

Thank You

I am getting this error….... PDF.js v1.5.188 (build: 0e2d50f) Message: file origin does not match viewer’s

Hi, PDF Viewer for WordPress requires file origin to be exact same as viewer’s origin.

It means the file url must always starts with the same protocol as the url of viewer. So if your site url starts with http://www. , the file url must also start with http://www.

if your site url starts with https://www. , the file url must also start with https://www.

Same thing for only http:// or https://

Please let me know if you still having issue to understand this.


That was the problem. Cheers

Is it possible to turn the page navigation on as default? I would need it open when the page loads

You mean the navigation part on left side where there are bookmarks and attachments ?

If so, Yes you can turn that navigation on by default.

Plugin dasn`t compatible with All in one Wp Security. If Wp Security enabled, plugin admin page show page error 403

Hi, Probably that plugin is blocking the admin page for some reason. Try changing settings different settings in the security plugin and also create a ticket regarding this on our helpdesk. We’ll check and update you there.

Simply send an email to to create a ticket.


Can you add the option to disable copy/paste somehow in the future versions of this plugin? It’s great that it disables downloading of the file, but half the people viewing it will be able to figure out they can just highlight the content and hit CTRL+C to copy all the text they want into Word or something. Otherwise, it makes your plugin only a partial solution to the bigger problem. Thanks.

Hi, I see inside the iframe not pdf, but the dashboard… how I can resolve the issue ?
