title: Session Variables Not Carrying Over to Other Pages
body: <p>My first page is:</p>
  
  <pre><code>&lt;?php
  
  session_start();
  
  $_SESSION['test'] = 'testSession';
  
  ?&gt;
  </code></pre>
  
  <p>Other page is:</p>
  
  <pre><code>&lt;?php
  
  session_start();
  
  echo $_SESSION['test'];
  
  ?&gt;
  </code></pre>
  
  <p>There is no output on the second page. The error log outputs:</p>
  
  <p>[30-Oct-2013 12:13:53] PHP Warning:  session_start() [function.session-start]: Cannot send session cache limiter - headers already sent</p>
  
  <p>Are there any ideas as to what the problem might be? The session variables can be outputted fine on the first page (when I tested), but not on the second. Thank you.</p>
