I installed the test gallery and you're not gonna believe this, but it let me upgrade that one LOL. I think I've figured out what was wrong, though. I had the confic-inc file from my regular gallery open to see my DB settings (username, password etc) when I installed the testgallery, and I noticed that the path to the gallery came up different in the new install than in the regular one. The path in the new install says /data/www/vsite303/web/testgalleri while the path to the regular gallery says /www/0/3/vsite303/web/galleri
I was having server problems around Christmas and I think I must have been moved around a bit. One day the users couldn't upload pics, and I told my host. They were working on some other issues on my server at the same time, and all the other paths have been altered, except the path to the installation. So that's probably why it's been messed up, right?
The upgrade on the test install went well except for one thing - the admin-index.php comes up as white, but with the grey border that separates the menu from the page. I changed the stylesheet to one of the included ones in phpmyadmin, in case my self-made stylesheet didn't work with the newest version, but it's still the same. Do you know how I can fix this? I need to rebuild the thumbnail of the pic I uploaded as a test. Now I'll know what I need to do before I upgrade the regular gallery LOL
The testgallery is located at http://www.scrapbookexpress.no/testgalleri/
and has the same admin info that I PMed you yesterday.
Thanks again for your help!
