Hello! I have the same problem on my site. Update the plugin to the latest version "Yjsg Framework Plugin v2.2.5" and have stopped working elements showing videos.
In the template editor, I have activated the option to display media "MediaElement Settings> Turn on MediaElement> Yes"
That could be happening?
Thank you very much for your help
