Hi Steph,
there is an error when a user tries to log in with an openid (http://wordpress.org/extend/pl…..ns/openid/) and has no account yet.
TOU reports "The requested URL /profile.php was not found on this server.".
That's OK since there is no user account. It would be great if your plugin goes back to the login or to the landing page of the blog without showing the error
