By default, the only fields required in the back-end (e.g when adding a new user, or editing a profile) are: Username, E-mail, Password and Repeat Password. This is the default WordPress functionality, not related to Profile Builder.
Were you referring to these fields, or others?
No. The fields I refer to are the extra profile fields added via Profile Builder and set as required.
Thanks for explaining this in more detail. There’s an action which you can remove to disable all required fields in the back-end.
remove_action( 'user_profile_update_errors', 'wppb_validate_backend_fields', 10);
Add the code above in an empty plugin or your theme’s functions.php file.
