Trackback error with Decker theme

I have been using Decker theme by DBT. It has one problem, whenever there is a trackback for post, it simply gives trackback error and the sidebar also doesn’t show up only. Below is the comment.php code:

<?php
$req = get_settings(‘require_name_email’);
if ( ‘comments.php’ == basename($_SERVER[‘SCRIPT_FILENAME’]) )
die ( ‘Please do not load this page directly. Thanks!’ );
if ( ! empty($post->post_password) ) :
if ( $_COOKIE[‘wp-postpass_’ . COOKIEHASH] != $post->post_password ) :
?>
<div><?php _e(‘This post is password protected. Enter the password to view any comments.’) ?></div>
</div>
<?php
return;
endif;
endif;

?>
<?php if ( $comments ) : ?>
<?php global $sandbox_comment_alt ?>

<?php
$ping_count = $comment_count = 0;
foreach ( $comments as $comment )
get_comment_type() == “comment” ? ++$comment_count : ++$ping_count;
?>
<?php if ( $comment_count ) : ?>
<?php $sandbox_comment_alt = 0 ?>

<div id=”comments-list”>

<h2><?php printf($comment_count > 1 ? __(‘<span>%d</span> Comments’) : __(‘<span>One</span> Comment’), $comment_count) ?></h2>

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

?></div>
<?php if ($comment->comment_approved == ‘0’) _e(“\t\t\t\t\t<span class=’unapproved’>Your comment is awaiting moderation.</span>\n”) ?>
<div class=”comment-content”>
<?php comment_text() ?>
</div>

<?php endif; ?>
<?php endforeach; ?>
