Could it be because you have UBBT and UltimateBB in the same directory? Maybe the UBBT is trying to read the Ultimate cookies? (Or the Ultimate is corrupting the UBBT cookies?) Also, I noticed you are running your forums in a subdomain (forum.foolmoon.com). I think someone else posted they had a problem running their board in a subdomain as well.
Even with 2 separate versions of threads, I had problems running it in two different directories on the same domain (unless we wanted to set cookies directory wide and not site wide, which we didn't.
) I ended up setting everything up and getting everything ready on my private (read: cheap and tiny
) website, then when we move the new version over this week I'll set it up in a new directory to hook up to the mysql, run the altertables, then make the move to the regular directory. Yes, it's definitely the long way around, but our users are very particular about down time (they get antsy over 10 minutes of downtime
)
These probably aren't your problem, but at least it's something more to rule out!
