Facebook SDK returned an error: Cross-site request forgery validation failed. The “state” param from the URL and session do not match

Question

i\'m trying to get Facebook user id using the php sdk like this

$fb = new Facebook\\Facebook([
    \'app_id\' => \'11111111111\',
    \'app_secret\' =>         


        

Answer 1

I had the same error, because I forgot to add "www." to the sender address. In the Client-OAuth Settings there has to be the correct name.
