The user who is allowed the Save as Site Default button must be an Administrator and must be a Super Adminstrator via the config.php file:

PHP Code:

    //    ****** SUPER ADMINISTRATORS ****** 
    //    The users specified below will have permission to access the administrator permissions 
    //    page, which controls the permissions of other administrators 
$config['SpecialUsers']['superadministrators'] = '1';
