I am using Image Manager extended. Since a while (after a major update I think), the Popup to create Ligtbox images tab has disappeard. I have now installed MediaBox (was that the right thing to do? Or should the Popup function already be included in Image Manager Extended?). But there is still no Popup tab.
By the way, I've activated the MediaBox plugin. But I see no change after that except that it appears in the control center as new tile.
