Forum "Sorry, you do not have permission to access this page." after upgrade
 

It seems that after I upgraded to v4.0.4 from 4.0.3, some of my forum categories no longer work. I have checked the permissions and they seem fine but they give me no-perm errors when not logged in.

For example, visiting http://atheistdiscussion.com/vbcms-c...on-peace-5162/ gives me the message "Sorry, you do not have permission to access this page." and when I view the vbcms-comments section located here: http://atheistdiscussion.com/vbcms-comments-33/ it says "Invalid Forum specified. If you followed a valid link, please notify the administrator". When I'm logged in, it works fine though.

Any suggestions?
