Same trouble here ? Any update ?

Looks like the developers have lost interest in supporting this plugin. The fix would take no effort.

Last updated: (over a year ago)
1.4.7 – 2019-07-03

And this message:
This plugin hasn’t been tested with the latest 3 major releases of WordPress.

Issues is outdated jQuery code:
jQuery.fn.size() is deprecated; use the .length property

If you have FTP access, you can download, fix, and upload these three files:
/wp-content/plugins/pdf-light-viewer/resources/assets/js/magazine.js
/wp-content/plugins/pdf-light-viewer/resources/assets/js/admin.js
/wp-content/plugins/pdf-light-viewer/resources/assets/js/quick-edit.js

replace “.size()” with “.length”

Thanks Ray, that helped. An easy job. ??

Thank you, @raywjohnson

@skoen @joskevermeulen @johnccg I also added a fix to 1.4.8

Perfect. I’m marking this as solved.

You are most welcome! @antongorodezkiy

Hmmm….

An update for the plugin and it is back where it was? I have to do the replace “.size()” with “.length” of Ray (thanks Ray!) What was the purpose of the update? ??

Strange, it should be there – https://plugins.trac.www.ads-software.com/browser/pdf-light-viewer/tags/1.4.8/resources/assets/js/magazine.js#L15

Indeed strange, this is what I get now:

Hello again,

I thought I download the PDF Light Viewer PRO Addon and the PDF Light Viewer Serverless Addon from CodeCanyon and reinstall it. But the PDF Light Viewer PRO Addon can’t be installed. It always says: The link you followed has expired. Please try again.
The PDF Light Viewer Serverless Addon installed perfectly.

@joskevermeulen I see – that’s from Pro Addon. Please email us the link you’re trying to use or screenshot to the [email protected].

Thanks, I did send you an email.
