I recently upgraded from one SM server to another and have just begun experiencing this problem.
Everyone can get to http://allalias.com and basically everyone can get to http://allalias.com/forums/ but for a lot of people http://allalias.com/affiliates and http://allalias.com/guide/ won't work most of the time. http://forums.allalias.com works for most people most of the time to get the same as /forums/.
Any ideas on what could be causing this?
Thanks!
