title: Opera & PHP Sessions Problem
body: <p>I have a login script that works fine in IE and FireFox but in Opera I can sometimes stay login for a couple of pages and then I'm logged out or something or I can't log in at all.</p>
  
  <p>Can someone explain why this might be happening and how can I fix it?</p>
  
  <p>Here is my code for my sessions at the top of my header.</p>
  
  <pre><code>$title = 'page title';
  ob_start(); // Start output buffering.
  session_start(); // Initialize a session.
  </code></pre>
