I can't change the settings for this because it gives me

I can't change the settings for this because it gives me the following error on the network settings page

Please edit your /nas/wp/www/cluster-40906/foodzubeuk1/wp-config.php and move the line define( 'SUNRISE', 'on' ); above the last require_once() in that file or make sure you updated sunrise.php.

I don't have access to that and can't change it. Can you help?
