@Jonathan – Do you have a folder in your install named ‘forums’ that might be conflicting? Do you have BuddyPress installed and is it using the default ‘forums’ slug for its forums component? Did you do any rewriting in your .htaccess file regarding the forums slug? Have you tried visiting your permalinks settings and resaving them to see if something is just out of alignment?
