No verification email being sent

I just installed the URSP. I am able to get to the register page (users_Registration.php) and enter all the information.

When I click the Register button, it accepts the information, and returns to the same form, which is now empty. No verification email is sent, and I am not sent to the users_ThankYou.php page. The page is updating the database with a new record with all the information, so the database connection is working fine.

If I try to log in (users_LogIn.php) I just redirect back to the same page after entering correct login information. The same thing happens if I enter a bogus email/password.

If I go to the forgot password (users_EmailPW.php) and enter an email address that is in the database (registered but not verified) I DO get an email with the login password.

I have not changed anything on the original files except the WA_Globals.php, but I did apply my site template to the original PHP files. One concern that I had was that when I was applying the template, I was prompted with a dialog titled "Inconsistent region names" which wanted me to resolve two regions: Document body and Document head. I resolved the Document body to "content" and the Document head to "head". That applied the template correctly, but I don't know if that messed something else up.

Hoping for help soon...
