Fixed code error. This will now work.

find

PHP Code:

    SELECT COUNT(postid) AS ppforum, thread.forumid AS forumid
    FROM post
    LEFT JOIN thread ON thread.threadid = post.threadid
    WHERE userid = '$userinfo[userid]'
    GROUP BY (forumid)
    DESC LIMIT 1"); 


replace with

PHP Code:

    SELECT COUNT(postid) AS ppforum, thread.forumid AS forumid
    FROM post
    LEFT JOIN thread ON thread.threadid = post.threadid
    WHERE userid = '$userinfo[userid]'
    GROUP BY (forumid)
    ORDER BY ppforum
    DESC LIMIT 1"); 


I added by ORDER BY so that it will give you the higest post number instead of the forumid T_T
