I have found it:

search in showflat.inc.php:

PHP Code
	 $userstatus = "";
		$userstatus = $html->user_status($usernum,$gimages);

and edit to:

PHP Code
	 $userstatus = "";
		if ($PostStatus == "Administrator") {
			$userstatus = "<img src=\"{$config['BASE_URL']}/images/groups/adm.gif\" alt=\"{$ubbt_lang['USER_ADMIN']}\" border=\"0\" />";
		}
		elseif ( ($PostStatus == "Moderator") && (stristr($modcheck,",$usernum,")) ) {
			$userstatus = "<img src=\"{$config['BASE_URL']}/images/groups/mod.gif\" alt=\"{$ubbt_lang['USER_MOD']}\" border=\"0\" />";
		}

It Works! smile
