Hi again!
I make a change at function findIdentity($delegations=0) from openid.php to run ok. I only comment the next line:
return $this->findIdentity($delegations+1);
This line causes a recursive loop and avoid to follow the next step, check for server.
Only I have a problem: the logout process seems to not work and still registered like OpenID user though appears the login form!
Best,
Xavier
