Thank you for the solution! Just a question.... messages like "Password Sent. Please check your email" are opening in new page with error :

This XML file does not appear to have any style information associated with it. The document tree is shown below.
      <string>Can't find a user with that email address</string>

The message was supposed to be displayed in the same page ( ForgotPassword.cshtml )???

Thanks
George
