Modificar single.php para añadir Facebook Comments

Buenas, estoy usando Techtástico con un servidor windows (osea, sin cURL) por lo que los pluggins de comentarios que he usado no me dan resultado (de hecho tengo un puesto ahora y no sale la opcion de comentarios db http://www.mundomariah.com/wordpress/index.php/2011/12/20/video-especial-merry-christmas-from-mariah-carey/).

El caso es que he visto que se puede hacer sustituyendo en el archivo single.php, pero no he visto el código que ponen que hay que sustituir

<div id=”comment”>
<?php comments_template(); ?>
</div>

dentro de mi archivo single.php

<?php
/**
 * @package Themetastico
 */
?>
<?php get_header() ?>

	<div id="content-box">
