Ok, here is the piece of code

// <!-- TOP POSTER -->
	$topposter = $DB_site->query_first("
		SELECT username,posts,userid
		FROM " . TABLE_PREFIX . "user
		ORDER BY posts
		DESC LIMIT 1
	");

	// <!-- TOP THREAD STARTER -->
	$topstarter=$DB_site->query_first("
		SELECT COUNT(*) AS count,postuserid,postusername
		FROM " . TABLE_PREFIX . "thread
		GROUP BY postuserid
		ORDER BY count
		DESC LIMIT 1
	");

At least I think it is...

BTW, I tried to set my lanuage to english but even though, the link to the members profile is still wrong. The link doesn't show up like:
www.forum.url/forum/member.php?u=3512
it shows like:
www.forum.url/forum/member.php?u=3,512 (<-- see the comma?)

When I turn it back to german, I have a dot there instead of the comma, which is the german separator for a thousand.

This also happens with topposter, Most Viewed Profile and Top Referrer. With the welcome newest member it is fine. In both languages.
