    i don´t get what you want.
    Have you tried to delete your browser cache & cookies? What happen if you reload the page instead of hitting the back button?

    That's because the session has closed. When you hit the back button, it goes back to the previous page as it was when it was loaded. The page has therefore, expired.

    // log out if no session
      if (!isset($_SESSION['UserName'])) {
        if (isset($_SESSION)) {
          while (list ($key, $val) = each ($_SESSION)) {
            session_unregister($key);
          }
          session_destroy();
        }
        header("Location: ../index.php");
        exit();
           
      }
    PHP:
    That's session.php?
    If so, add before all a session_start();

    Thanks all
    if I reload or click the back button I get the same error, really I don't know how to delete browser cache & cookies.
    if I submit a form to another page and I need to back the page of form by clicking the back button of the browser I get " the page has expired "
