After submitting the user register form, as anonymous user, I get this error "SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '526' for key 'PRIMARY': INSERT INTO multiple_registration".
This happens because the _multiple_registration_rid() is trying to insert a new record in multiple_registration table, but there is already a record that inserted from multiple_registration_update_registration_table().
1) Install and configure Multiple Registration
2) Try, as anonymous user, to insert a new user from the user registration form.
