well, where do you get the $thread[pollid] value in your iif-clause?

are you sure it's already set?

try to use this code:

$threads=$DB_site->query("
  SELECT thread.*,user.usergroupid FROM thread LEFT JOIN user ON (user.userid = thread.postuserid)
   WHERE open=1 $iforumperms ORDER BY lastpost DESC LIMIT 5
");

btw. i have modified your where clause, it's not nessesary to use open<>10 when you already have open=1


well 15 queries is not so much, i don't see if you really need two, perhaps one is enough. Can you post the full part of the script?
