Just created new registration
Two sending failures occurred:
(1) It did NOT send me an initial email acknowledging that I had registered, and sending me a first verification email
(2) It did close the registration page, and it did send me to the login screen.
(3) I logged in and then opened up the relevant profile quite OK (I did not go to some wrong screen).
(4) But when I clicked at the top of profile page to request confirmatory verification email (which should have been the second one) I was confronted with a whole screenful of debug information.
(5) I still do NOT receive a verification email at that given email address.
