Hi there,
I am getting this problem (which I think was always there as my site is offline most of the time) who basically does not allow a user to use their email to login. When a user is about to login, they are asked to add:
Your username or email address
However, if I put in my email address and my password, I get this message
Error; This email is already registered
If I then use my username and password, it does allow me in!!
