hi christy -
thanks for writing - i read that kbase page and i don't remember seeing that .htaccess advice there, how strange! - anyway, that's just what support suggested earlier today, and it worked, sort of - i got all the way through the configuration process and then when i tried to log in to the gallery itself i got another error:
Warning: fopen("/home/myusername/mydomain/gallery/albums/.users/userdb.dat.lock", "a+")
- Permission denied in /home/someDHaliasthing/myusername/mydomain/gallery/platform/fs_unix.php on line 53
Error: Could not open lock file (/home/myusername/mydomain/gallery/albums/.users/userdb.dat.lock)!
when i looked at the contents of the .htaccess file, i saw that the configuration process had overwritten it with some other stuff - the AddType stuff wasn't there anymore. did you experience anything like this?
