My "Start update thread count" section in "functions.php"
compares ok with the original "functions.php":
*******************************

PHP Code:

function updatethreadcount($threadid) {
  global $DB_site,$threadcache;

    $replies=$DB_site->query_first("SELECT COUNT(*)-1 AS replies, SUM(attachment.visible) AS attachsum
                                    FROM post
                                    LEFT JOIN attachment ON attachment.attachmentid=post.attachmentid
                                    WHERE threadid='$threadid'");

    $lastposts=$DB_site->query_first("SELECT user.username,post.username AS postuser,post.dateline
                                      FROM post
                                      LEFT JOIN user ON user.userid=post.userid
                                      WHERE post.threadid='$threadid' AND visible>0
                                      ORDER BY dateline DESC
                                      LIMIT 1");
    $lastposter=iif($lastposts['username']=="",$lastposts['postuser'],$lastposts['username']);
    $lastposttime=$lastposts['dateline'];

    $firstposts=$DB_site->query_first("SELECT post.userid,user.username,post.username AS postuser,post.dateline
                                       FROM post
                                       LEFT JOIN user ON user.userid=post.userid
                                       WHERE post.threadid='$threadid' AND visible>0
                                       ORDER BY dateline
                                       LIMIT 1");
    $firstposter=iif($firstposts['username']=="",$firstposts['postuser'],$firstposts['username']);
    $firstposterid=$firstposts['userid'];

    $DB_site->query("UPDATE thread SET postusername='".addslashes($firstposter)."',postuserid='$firstposterid',lastpost='$lastposttime',replycount='$replies[replies]',attach='$replies[attachsum]', lastposter='".addslashes($lastposter)."' WHERE threadid='$threadid'");

}

Does that mean that it is in the mySQL the problem is?
