My Checkout Without Account Mod

[craftzombie]

Which login? includes/modules/pages/login/header_php.php?

What code looking for to disable?

No, the template for the login page....
includes/templates/your_template/templates/tpl_login_default.php

The following code is what makes the Guest Checkout section appear on that page:

<?php
  if ($_SESSION['cart']->count_contents() > 0) { ?>
    <fieldset>
    <legend>Checkout Without Account</legend>
    <?php echo TEXT_RATHER_COWOA; ?>
    <div class="buttonRow forward">
    <?php echo "<a href=\"" . zen_href_link(FILENAME_NO_ACCOUNT, '', 'SSL') . "\">"; ?>
    <?php echo zen_image_button(BUTTON_IMAGE_CONTINUE, BUTTON_CONTINUE_ALT); ?></a></div>
    <br class="clearBoth" />
    </fieldset>
<?php } ?>
