User email address does not save Settings -> General -> Email.
I enter the email address click Set email.
Message "An email has been sent to this address for confirmation" in green is displayed.
Confirmation email is also received.
But when you go back to Settings -> General -> Email the email is not there.
Also when trying to reset the password no reset email is received.
Message in the log file "Could not send reset email because there is no email address for this username"
