Drupal User Creation SMTPS message fails

Question

I'm using Drupal 7. When I add a user via Peoples > + Add User, I want the user to receive a notification e-mail.

If I tick the box: " Notify user of new account ", and then click "Create New Account", the page redirects to a blank page at "/admin/people/create". The user IS created, but no message is sent. There isn't even a log for an attempt to send an SMTP message in Drupal, or a failure etc. But the user exists.

If I DON'T tick the box, then the user is still properly created, but I don't get stuck at a blank page (the page is refreshed and I can see the green checkmark saying my changes have been applied)

How can I investigate this problem? I would like the e-mail to be sent (and I assume the blank page problem is related/the same issue) Like I said, I see no logs of e-mail trying to be sent, but it only crashes when I try to do so. Perhaps there's some other logs/debugging info I can enable?

Thank you very much,

Found my problem. The Token module was broken, and my user registration message used tokens, so this is why it crashed on user registration but not SMTP test.

Re-installing a fresh copy of the Token module fixed it.
