I deleted a thumbnail within elFinder (it allowed me despite there was a lock symbol attached to it. Get Info didn't report it to be locked, though).
Now thumbnail function seems to be broken at all.
When I delete the thumbnail folder a new one will be created @ next image upload. But no thumbs will be created anymore.
Have tried all sorts of permissions but didn't change anything.
@feniweb - Can you try to recreate the same problem on this installation ?
I would be interested in knowing what the folder rights/permissions are of the newly created directories, but I also wanted to mention that there was a problem with the way gpEasy was trying to create thumbnails in 3.5b1 and 3.5b2. I'm not certain it will solve this problem, but there's a chance and at the latest, gpEasy 3.5rc1 should be out early next week.
