Hi @yaniv691,
Thanks for clarifying that and providing those details. It seems the issue has to do with the external load method loading the popover code after the page is loaded through AJAX.
That I see, you'd have to somehow load that ravello.js with that method as well and I don't see a way except to edit the plugin's core files.
If you wish to give something a try, you could try copying and pasting the code from ravello.js onto the end of the popover's main JavaScript file at:
\plugins\wordpress-popup\popoverincludes\js\popover-load.js
Is that something you'd be wiling to try out?
