 * This is the 404 page template for the "Error 404" skin.
 *
 * This skin only uses one single template which includes most of its features.
 * It will also rely on default includes for specific dispays (like the comment form).
 *
 * For a quick explanation of b2evo 2.0 skins, please start here:
 * {@link http://b2evolution.net/man/skin-development-primer}
 *
 * The main page template is used to display the blog when no specific page template is available
 * to handle the request (based on $disp).
