File gallery thumbnails lost after upgrade to 6.12 LTS
Hi,
I just upgraded my version 6.7 LTS to 6.12 LTS. Everything went smooth - execept for the thumbnails in the file galleries.
They are all gone. And worse, new images I put there do not receive thumbnails either. During installation of the upgrade (I copied files over and ran the installer) GD was detected. Also, the test image on the _image_ gallery setup page (I do not use image galleries because they are deprecated) does show up.
Also, it's no problem to view the images, new and old. Thumbnails of gallery images embedded on some wiki pages do show, however. Only in the file galleries itself they are missing.
I store images not in the DB, but in a directory (imagestore). The memory limit is 90 MByte. PHP is 5.2x.
On some threads here I read something about a thumbnail-regeneration button, but I cannot find that. Possibly it only exists in newer versions...
Thanks alot!
Oliver
