Trackbacks not displaying :'(

Good morning,

I’m running WP 2.7 with the Sandbox them [which I highly customized] for my webzine.

For the Comments template (comments.php), I deleted Sandbox original one and used my blog’s instead [my blog is using Big Blue theme].

The problem is, if a single post actually has trackbacks, they do not display among the comments: worse, the number of comments does not count the trackbacks in the comments template. The strange thing is that:

1/ I’m absolutely sure there is one trackback: I got notified by email and I can see it in the admin;

2/ the comments_count() function does tell there is N comments + 1 trackback!

Cf. this post, which did get a trackback yesterday night:
https://www.lalunemauve.fr/musique/news-musicales/sorties-cd-dvd/premier-album-de-spleen-arcana-the-field-where-she-died/

Thus the problem must be in my comments template [which I replaced many times with different templates, with no success]. Here’s the one I’m using:

<?php // Do not delete these lines
	if ('comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Ne chargez pas cette page directement SVP. Merci!');

        if (!empty($post->post_password)) { // if there's a password
            if ($_COOKIE['wp-postpass_' . COOKIEHASH] != $post->post_password) {  // and it doesn't match the cookie
				?>

				<p class="nocomments">Ce billet est protégé par mot de passe. Saisissez le mot de passe pour voir les commentaires.

				<?php
				return;
            }
        }

		/* This variable is for alternating comment background */
		$oddcomment = 'odd';
?>

<!-- You can start editing here. -->

<div class="boxcomments" id="bottom">

<?php if ($comments) : ?>

<?php 

	/* Count the totals */
	$numPingBacks = 0;
	$numComments  = 0;

	/* Loop through comments to count these totals */
	foreach ($comments as $comment) {
		if (get_comment_type() != "comment") { $numPingBacks++; }
		else { $numComments++; }
	}

?>

<?php 

	/* This is a loop for printing comments */
	if ($numComments != 0) : ?>

<div id="comments-title">

Can anybody help me, please? (And yes, the “show trackbacks” options are all on.)

Thanks a lot in advance!
