Hi do you use analytics with this plugin. I have filled my UA code but there no manual for setting it up. Is there a event created or…?

Hi, The tracking code is placed in all the viewer pages automatically when you put the tracking code in place.

Hi Your given link is not working ! My Question is – 1). I can’t attach direct pdf into WordPress page, We need to go and generate a link then copy into button of plugin. For many files it’s a hard work. If we can select direct a PDF file into WordPress page, It’s little better. SO short code generating is very difficult. 2). The plugin don’t have LightBox system. How visitors can understand without front page seeing. Something like here ( ) 3). I can’t select two or morethan two files in once for short code. Otherwise please provide me my refund. Thank you :)) Be Healthy !!

How do I create shortcodes? It allows me to create a link, to the PDF file. I’m going crazy here looking for a very simple function..”CREATE SHORTCODE” . Easily create the shortcode, connected to the pdf file, then you copy and paste the shortcode on the page, post..And the viewer should appear, with the pdf. That’s the common sense way of doing it. Easy. But for some reason, this plugin, has no shortcode option. It’s not apparent, it’s not there in front of the user..I have no idea how to create a shortcode. Non-intuitive. Just a link.

A link to the pdf file..? Where is the shortcode for the pdf file, to copy and paste and allow the viewer to appear? Inquiring minds want to know.

Hi protonomos, I think you’re using it with latest WordPress. WordPress 5.0 comes with new gutenberg editor. We’re still in process of releasing the integration with gutenberg, But we have integration with classic editor which is just being replaced with gutenberg.

The workaround for easy shortcode creation is: 1. Install and activate Classic Editor plugin on the site 2. Follow the documentation to create shortcodes:

Is it possible to have the height be responsive also? On mobile there is a lot of unnecessary space at the bottom of the iframe. I just want a single page of the PDF to be visible with ability to skip to next page but have that view look good on all screen sizes (with the size of the iframe scaling proportionately).

Hi, Sorry, there’s no option for adaptive height.

Thank You
