title: Why am I not seeing any firephp output?
body: <p>I am trying to get firephp to work.  It was working as of last week and I don't know when
  exactly it stopped working or what I changed.</p>
  
  <p>I am now trying to do a simple firephp hello world. </p>
  
  <pre><code>&lt;?php
  require_once('FirePHPCore/FirePHP.class.php');
  ob_start();
  $firephp = FirePHP::getInstance(true);
  $firephp-&gt;log('Hello', 'World');
  
  require_once('FirePHPCore/fb.php');
  $var='test';
  fb($var);
  FB::send($var);
  
  ob_end_flush();
  ?&gt;
  </code></pre>
  
  <p>There is no result in the firebug console window and no error messages I can find.</p>
  
  <p>FireFox 5.0</p>
  
  <p>FireBug 1.8.0</p>
  
  <p>PHP 5.3.1</p>
  
  <p>Firebug console and net panels are enabled.  FirePHP is enabled.</p>
  
  <p>In the net panel under the get request, I do not see any X-wf- headers.</p>
