My gallery worked fine till today. Suddenly one album wasn't able to find the thumbnails and pictures in the directory. I always get the message, that the directory is not writable, but I checked on my server, the directory has full access (CHMOD 777).
I reinserted the pictures without any problems, he didn't create new thumbnails. These pictures i can delete, but not the original ones.
And that's the album:
http://gallery.thematti.com/thumbnails.php?album=40

Problem solved: reinserted the new ones, and deleted the entries in PHPMyadmin.
