title: Facebook require_login not working
body: <p>I am having some trouble with my little facebook application, I keep getting this friggin error, "Fatal error: Call to undefined method Facebook::require_login()", now the funny bit is that my exact same code is working for other people, but not for me, here is the code.</p>
  
  <pre><code>&lt;?php
  require_once( "facebook-php-sdk/src/facebook.php" );
  $api_key = "my_api_key";
  $secret = "my_secret_key";
  
  $facebook = new Facebook( $api_key, $secret );
  $user_id = $facebook-&gt;require_login();
  
  echo "Hello World";
  echo "Current logged in as &lt;fb:name uid=\"$user_id\" /&gt;";
  ?&gt;
  </code></pre>
  
  <p>As you can see it is a simple hello USER application, but for some reason this REFUSES to work for me, so if anyone can help out that would be great, thanx in advance!</p>
