I get this error when running cron job manually:

Fatal error: Call to a member function query_read_slave() on a non-object in /home/XXXXXX/public_html/forum/includes/functions.php on line 8503

functions.php: lines 8503-8598

$data = $db->query_read_slave("
		SELECT *
		FROM " . TABLE_PREFIX . "navigation
		WHERE state & " . NAV_DELETED . " = 0
		ORDER BY navtype, displayorder
	");

Edit:
If I turn off "Enable PM's" this error does not show.
