title: Unable to Access User's email. Getting "Undefined"
body: <p>I have a website with the Facebook login implementation. My app has the permission for the user's email.
  Even though the user logs into my app using Facebook I can only retrieve his/her name or basic info. Not the email.
  So, here's the code I literally copied from the Facebook Developers Website:</p>
  
  <pre class="lang-js prettyprint-override"><code> window.fbAsyncInit = function() {
  FB.init({
  appId      : 'xxxxxxxxxxxxxxx', // App ID
  channelUrl : '//domain.org/channel.html', // Channel File
  status     : true, // check login status
  cookie     : true, // enable cookies to allow the server to access the session
  xfbml      : true  // parse XFBML
  });
  
  
  FB.Event.subscribe('auth.authResponseChange', function(response) {
  
  if (response.status === 'connected') {
  
    testAPI();
  } else if (response.status === 'not_authorized') {
  
    FB.login();
  } else {
  
    FB.login();
  }
  });
  };
  
  // Load the SDK asynchronously
  (function(d){
  var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
  if (d.getElementById(id)) {return;}
  js = d.createElement('script'); js.id = id; js.async = true;
  js.src = "//connect.facebook.net/en_US/all.js";
  ref.parentNode.insertBefore(js, ref);
  }(document));
  
  
  function testAPI() {
  console.log('Welcome!  Fetching your information.... ');
  FB.api('/me', function(response) {
    console.log('Good to see you, ' + response.email + '.');
  });
  }
  &lt;/script&gt;
  </code></pre>
