If you don't need a registration page anymore, contact support@ukmsl.com and let us know which registration page(s) you want to deactivate.
You can access this feature from your MSL Admin site. Only Super Admins with Site Admins permissions can access the Registration Pages windows, and only MSL has the permissions to update the fields.
If you've deactivated all registration pages, edit your website's Login widget and deselect the Show Registration Link checkbox so the Register New Account link is no longer displayed.
For further information, see Registration Pages.
