Hi,  I am trying to handle a form submit using the JQuery ajax function. However, the following always results in a 404 page not found error: <?php     $subscribe = $config->paths->templates . 'includes/partials/' . 'subscribe.php'; ?> [...] $.ajax({       url: "<?php echo $subscribe ?>",        data: $('#subscribe').serialize(),       type: 'POST', [...]   After submitting the form, I always get the following error in Google Chrome's page inspector:   Including PHP
