I have (5) Profile Types for a current project one of those is a No-Membership ProfileType.
The only way to be put into this group is if you signup on the site for a membership and let it expire or decide to cancel your membership. With that being said a user in this ProfileType needs all rights stripped in the ProfileType ACL section but when I set everything to limited and 0 and save it will not keep the settings.
Please check on your end SI Team.
Thanks,
James
