I just found out why this is happening. In order to install our shopping cart software, they had to turn off Suexec. I quickly turned it back on and the board was working. Unfortunately, there's I have to keep it off in order to use the shopping cart. Is there a workaround? Also, we have several other sites on the same server running UBB that were not affected. Any idea why this one board would have a problem and not the others?

Thanks!
