After having migrated. I'm finding that redirect to vB4 forums that were categories are failing as XF category nodes. One particular category forum has great SEO. It's the number one google result for the search terms, but when you click on it \n\nhttp://my.url/forumdisplay.php/[forum_id] \n\nis being redirected to \n\nhttp://my.url/community/forums/[forum_id] \n\nwhich results in an error page. What can I do?\n\nThanks.
