Concrete5 version 5.6.3.4 POPUP problem
PermalinkMy website under concrete 5 versin 5.6.3.4 doesnt allow popups to open with a youtube video inside, the popup opens up but empty. Can you help please? Im using POPUP PRO. Thank you

It's possible that this block has http hard coded and your site is https and is blocking the video.
There are a lot of other things it could be too, but without a link to the site or any additional information (or access to the Popup Pro package) it's difficult to tell.
