We are using the template SiteRegistration Sites VF page to allow users to login. And made a minor controller code change to the PORTAL_ACCOUNT_ID as per instructions on : http://wiki.developerforce.com/page/Authenticating_Users_on_Force.com_Sites
We successfully register one user, but after the 2nd attempt of a another new user, we get the message 'You are already logged in'
We used the template, made only a minor change. What did we do wrong?
We are thinking it may be that we can't re-use the same account id? But has anyone else got this before?
