problems approving uploaded images

[warlock]

hi,

i've got some uploads and if i want to approve thema, i alwas
get "You don't have permission to access this page." and
get logged out, so i have to log in again. everything else
which requires adminmode works fine, just approval fails.

i've updaed cpg multible times, and never tested approval
between them. so i dont know since when this problem
exists.

some minutes ago i switched to cpg145 and the problem
still resists, so it shouldn't be a problem with the files.
i also already flushed the cpg_sessions table in the db.

anybody an idea?

regards,
michael
