Add Menu Item

[AngryDragonflyStudios]

Every time i go to add menu Item option, it just goes to a blank page (Still with my template and menu) I fixed this in the past i believe through some research that is not around anymore but forgot how i fixed it. Can anyone out there help?

In classes/customform.php, in function __construct(), it should be new Basic instead of new BasicSort for 2 of the lines.
