I wanted to post a problem that I had and a fix I had for it that I didn't see that others came across. First of all I had my at forum.domain.com is a subdomain of domain.com. So I would link to the forum using the subdomain address. When I would go to the site, everything would work fine, and the links would all be static. Then when I would login, my links would change back to the dynamic links (the links where it has the '?' at the end falued by name/value pairs). The problem was that the links would change from forum.domain.com to domain.com/forum/... So when I would log back out I was getting static links at domain.com/forum/... instead of static links at forum.domain.com, like what was working when initially going to the page & being logged out.
In order to fix this problem:
1: login as the administrator
2: under 'General Admin' click on Configuration
3: change domain name to 'forum.domain.com'
4: change script path from '/forum/' to '/'
Oh yeah, & my subdomain is forum, so if you have some other subdomain lik myforum or whatever, just replace forum to myforum. So your domain would be myforum.domain.com instead of forum.domain.com.
I hope this helps others that have a similar problem to what I had.
