XF 1.5 Problems adding new users

[NCNightmare]

When I try to add new members to my forum I get this error message and they can't be added. I also tried to register an account as if I was a new user and I never got a confirmation email.

"The server responded with an error. The error message is in the JavaScript console."

Can anyone help?

Press F12 to activate the browser console then select the Console tab.

There should be an error message.
