forumhome: PM Queries optimization!

[N9ne]

I have this:

$allpm=$DB_site->query_first("SELECT COUNT(*) AS messages,
SUM(IF(dateline>$bbuserinfo[lastvisit] AND folderid=0,1,0)) AS newpm,
SUM(IF(messageread=0 AND folderid=0,1,0)) AS unreadpm
FROM privatemessage WHERE userid=$bbuserinfo[userid] $ignoreusers");

$newpm['messages']=$allpm['newpm'];
$unreadpm['messages']=$allpm['unreadpm'];

Which looks the same! However it still doesn't show 0 for unread and new PMs! Why is it doing this? Is there anything in index.php that could cause this? [i have modified it a tiny bit, but not the PM bits :S]
