I'm having the same problem. I am getting "internal server error" but it's definitely not a permissions thing. I've set the permissions like the cfg file says, but no luck. Maybe it would help if someone could just tell us which file to open first... I had buckets of problems using an older version of OJ, but finally got it to work. I am configging this new version for a new site, but now I'm running in to more, different, birck-wallish problems. Like, I'm not an idiot, I've checked the obvious stuff (paths, domains, permissions - even set them all to 777) but no luck...
