[LifesGreatestGift]

First off, make sure your userid is set in includes/config.php to be able to run queries

	//	****** USERS WITH QUERY RUNNING PERMISSIONS ******
	//	The users specified here will be allowed to run queries from the control panel.
	//	See the above entries for more information on the format.
	//	Please note that the ability to run queries is quite powerful. You may wish
	//	to remove all user IDs from this list for security reasons.
$config['SpecialUsers']['canrunqueries'] = '1';
