Hi there,

I am trying to get OpenID authentication working and for the most part
seems to have gone fine except, when authentication I keep getting:

undefined method `relative_url_root’ for ActionController::Base:Class

I am testing from my local machine on Windows Vista using Mongrel. Any
ideas why I am getting this error?

Thank you in advance,
