I deactivated SP and upon reactivation I can see the list of forums but clicking onto the forum brings me to a 404 rather than the topics. http://sledmass.com/forum/
UPDATE: After 15 minutes everything returned to normal… Thinking it could have been WP Super Cache.
you cannot use wp super cache on the wp page the forum appears… you need to go into its setting and tell it to ignore the forum page.. in this case /forum/
Same issue again, WP Super Cache is completely deactivated. The 404 issue has returned.
BTW, I misspoke earlier, WP Super Cache was always set to ignoring the forums.
so what is not working??? when I visit your site, I can visit forums and topics without problem…
