Can't change Settings

Hi,
I recentely moved a phpAlbum folder from a "test-folder" (on a customer's site) one level up (www.xyz.com/htmltest/album -> www.xyz.com/album). Everything works but the upload-manager, 'cause here the path isn't right anymore... and now, as I tried to change that (or anything else) at the main settings page, I can save without an error report (no error log either), but when I refresh the page - nothing happened!

I already changed EVERYTHING via ftp client to 777, no effect.

Thx in advance!
Gernot.
