This ticket https://www.joomlacontenteditor.net/support/forum/mediabox/116820-no-lightbox-in-joomla-5 was solved but now I'm working on another site and despite installing Mediabox and using Image manager Extended I don't get the pop-up tab. What am I missing this time?

Hi Ryan, I'm still struggling with the Mediabox, after re-installing everything I still don't get the lightbox.

Hi Ryan,

I'm getting a little desperate, I still don't get the Popups tab at https://meinbert.com/ and now I get 'initial' as values in the Margin settings. Do you have any suggestion what I might do?

The Mediabox was unpublished! Now everything works as expected.
