Just want to let you know that this problem has been fixed. My host (web hotel) has moved my forum to another server (still Mac OS X, but with different tools instead of Mac OS X server) and eveything is working like it's supposed to now. I don't know exactly what caused the problem but I'm Happy <img src="http://www.ubbdev.com/forum/images/graemlins/laugh.gif" alt="" />
