In Dokeos 1.8.6, we have removed (or better say "hidden") the official code field from the open registration form. Well, that's only logical since we suppose a normal, already registered, student will be registered through an Excel import sheet or some automatized way. But that might cause problems to some of you, so basically, the only thing you need to do to re-enable it is
- edit main/auth/inscription.php
- look for "official_code"
- uncomment the section containing this term
