Hi,
Basically, with the Login / Registration page, you will need to have a menu item accordingly. At this moment, you don't have these menu items so it will redirect to the 'NEGOZIO | SHOP' menu item ID: 1236. But that filter module is being assigned to this menu, so it will show in registration page.
I just tried to create a new menu item with type of VM Account Maintenance under 'NEGOZIO | SHOP' item and when you click to sign up / register, it will show the form only, not include sidebar modules.
