In DaDaBIK V 11.8, users self-registration stops working and asks for missing fields.
This is due to the introduction of (optional) privacy checkboxes in the form, that by default are hidden ($show_accept_terms_privacy_checkbox_registration_form = 0).
To make self-registration work again, you can either:
1) show the checkboxes ($show_accept_terms_privacy_checkbox_registration_form = 1) OR
2) Set them as not required ($accept_terms_privacy_checkbox_registration_form_required = [0,0,0]
