Trackbacks Refuse to Show Up

So I give up, I absolutely have no clue as to why I can’t get trackbacks/pingbacks to show up on a clients site. Here is the comments.php code:


<?php // Do not delete these lines

if ('comments.php' == basename($_SERVER['SCRIPT_FILENAME']))

die ('Please do not load this page directly. Thanks!');

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">This post is password protected. Enter the password to view comments.

<?php

return;

}

}

/* This variable is for alternating comment background */

$oddcomment = 'alt';

?>

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

<div class="commentsheader"><h2>Discussion - <?php comments_number('No Responses', 'One Response', '% Responses' );?> </h2></div>

<ol class="commentlist" id="commentlist">

<?php if ($comments) : ?>

<?php foreach ($comments as $comment) : ?>

<li class="<?php echo $oddcomment; ?>" id="comment-<?php comment_ID() ?>">

<div class="commentauthor"><?php comment_author_link() ?>

<?php if ($comment->comment_approved == '0') : ?>

Your comment is awaiting moderation.

<?php endif; ?>

</div>

<?php comment_text() ?>

<?php /* Changes every other comment to a different class */

if ('alt' == $oddcomment) $oddcomment = '';

else $oddcomment = 'alt';

?>

<?php endforeach; /* end for each comment */ ?>

<?php else : // this is displayed if there are no comments so far ?>

<?php if ('open' == $post->comment_status) : ?>

<!-- If comments are open, but there are no comments. -->

<li id="hidelist" style="display:none">

<?php else : // comments are closed ?>

<!-- If comments are closed. -->

<li style="display:none">

Comments are closed.

<?php endif; ?>

<?php endif; ?>

<?php if ('open' == $post->comment_status) : ?>

<div id="loading" style="display: none;">Posting your comment.</div>

<div id="errors"></div>

<div class="addcomment"><h2>Add Your Comment</h2></div>

<?php if ( get_option('comment_registration') && !$user_ID ) : ?>

You must be /wp-login.php?redirect_to=<?php the_permalink(); ?>">logged in to post a comment.

<?php else : ?>

Does anyone have any ideas? Supposedly the trackbacks are showing up in his database table, just not displaying.

Thanks in advance.
