UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support rebuild index option goes to blank screen

Also, I looked in some of my forum folders. The permissions on most of the cgi files in there were (777) but some were (666). But I think that's ok, isn't it?

-I cannot rebuild search index..
-I cannot update member post histories..
-Board generates blank screen often and for long periods of time...
