There is a problem with the queries, I found the solution:

In forumdisplay.php find this code:

PHP Code:

        $topthreads = $DB_site->query_first("
                SELECT COUNT(threadid) as threads, postusername, postuserid
                FROM " . TABLE_PREFIX . "thread
                WHERE forumid=$forumid
                GROUP BY postuserid
                ORDER BY threads DESC, dateline ASC
                LIMIT 1
        ");

        $topposter = $DB_site->query_first("
                SELECT user.userid, user.username, COUNT(post.postid) AS postcount
                FROM " . TABLE_PREFIX . "post
                LEFT JOIN " . TABLE_PREFIX . "thread ON (post.threadid = thread.threadid)
                LEFT JOIN " . TABLE_PREFIX . "user ON (post.userid = user.userid)
                WHERE thread.forumid=$forumid
                GROUP BY post.userid
                ORDER BY postcount DESC
                LIMIT 1
        "); 


Replace with this code:

PHP Code:

        $topthreads = $DB_site->query_first("
                SELECT COUNT(threadid) as threads, postusername, postuserid
                FROM " . TABLE_PREFIX . "thread
                WHERE forumid=$forumid  AND postuserid <> 0
                GROUP BY postuserid
                ORDER BY threads DESC, dateline ASC
                LIMIT 1
        ");

        $topposter = $DB_site->query_first("
                SELECT user.userid, user.username, COUNT(post.postid) AS postcount
                FROM " . TABLE_PREFIX . "post
                LEFT JOIN " . TABLE_PREFIX . "thread ON (post.threadid = thread.threadid)
                LEFT JOIN " . TABLE_PREFIX . "user ON (post.userid = user.userid)
                WHERE thread.forumid=$forumid AND user.userid IS NOT NULL AND user.username IS NOT NULL
                GROUP BY post.userid
                ORDER BY postcount DESC
                LIMIT 1
        "); 


That's all!

See ya.
