title: Email address is not getting fetched on Facebook Login
body: <p>I am using Facebook PHP SDK for making the user login into our Application. Along with basic details i have asked for extended permissions like email, location, work history etc..
  For most of the users, its working fine(i am able to get everything i am asking for). But for few users i am unable to fetch email id from facebook. </p>
  
  <p>My login url is generated using following code</p>
  
  <pre><code>$data['fb_url'] = $facebook-&gt;getLoginUrl(array('scope' =&gt; 'email, user_birthday, user_work_history'));
  </code></pre>
  
  <p>I tried to reproduce the same thing but setting my email to private(Only Me) mode but still i can fetch my email id since i am explicitly asking in extended permissions.</p>
  
  <p>I am at my wits end to understand or reproduce this error for my profile. But still for some users this problem does occur. And there is no way i can see their facebook profile. Any help will be appreciated. Thanks</p>
