Suddenly I can't use the "Media" file uploader in Full HTML CKeditor edit screen but can do in Filtered HTML edit screen
Solved! For some reason (most probably a bug) the Media module button wasn't added automatically to the Full toolbar even after I check-marked &quot;Plugin for inserting images from Drupal media module&quot; in &quot;Editor appearance&quot; at the desired profile's settings page.
So, What I did was after I check-marked &quot;Plugin for inserting images from Drupal media module&quot; I just went on to add the button manually from &quot;Available buttons&quot; to &quot;Current toolbar&quot; (see img), saved, cleared cache, and Vwalla - it worked again!
