Hello,
I am looking into setting up User Registration.
In the sample project, once a user is created, they are not given a default the default role (although the code seems to suggest this is what will happen) they are automatically made admins.
Also, even after logging out and logging in under admin, the admin can no longer edit any user and receives this error.
Ultimately I am looking to replicate the user registration, but also collecting the users first name, last name and email.
