OVERLOOKED DEBUG CODE
Decided to go carefully through everything again
(A) when registering with user_registration.php at the sisya link, the validation email received does NOT in fact contain a code to confirm email. The relevant field is left blank.
(B) When logging in to the profile to click the link there to get a validation email, the debug code is still infact, so it all shows immediately
Sorry to have overlooked these, don't know how that happened.
