This is not working for me as well!! Please advise!
UGH! My issue is a little different. I have it setup for an admin to approve a member. No notices are sent at all that way and I would like to get a notification that someone has registered so that I know when it happens instead of just the next time I login. As far as your issue goes, I am certain that the issue is that it has to be a front end registration using UserPro. Otherwise, you are dealing directly in WordPress rather than UserPro so the email is not sent. I am not getting ANY emails sent at all……blows! I was hoping that you had heard from someone regarding mail issues:-(
Did you find an answer to this??
