I have not create any user group. I have only the Administratos under the user->user groups.
So any user creation through my site, creates a customer.
The weird thing is that in the general tab of the products, the availability->user groups says : All - Guests - Registerd.
I did an “edit selected” for all products and checked the all option, but for some reason it is unchecked again? All the customers functions seem to work fine ! As registered user or as guest.
Should this box be checked under my group situation or not? And how important is this checkbox?
