Hello. I managed to add a new user in the database directly by adding a record in the table mp_Users. I also added a new record in mp_UserRoles based on the new user and added the appropriate RoleGuid to have it "authenticated". I can make the user log-in; however, the user cannot see the site menus even though his role is already  "Authenticated user". The only way I can make the user see the menus is by logging in as admin, deleting the existing authentication under Manage User > Role membership, and re-assign the "Authenticated user" role using the "Add user to this role" button. The effect it has on the table mp_UserRoles is exactly the same as when I encoded it manually in the database. I guess I am missing some database tables to modify. Do you have an idea what these may be?
