Redmine

After I already did some test installations, the final (time critical..) installation will not work. I can access the redmine webpage, but I cannot login.

I use apache + passenger. I can access /projects and /time_entries, but not /activity and I cannot login (after submitting user & pass, I get the Internal Error 500)
