Comments Not Showing Up

I’ve just started using wordpress and I thought I’d try my hand at making a theme for my blog. Everything is working fine except the comments. I tested the theme on my personal webserver and it worked but when I uploaded it to my site, the comments are not showing up. It just stays as “There are no comments currently.” SEE HERE. I suspect it might have something to do with the mod-rewrite permalinks (since I had a similar problem with the default wordpress theme which was later resolved by changing the permalink options around). Anyway, if someone can, please help me :/! Your aid is appreciated!
Here’s the code for comments.php:

<?php
// Do not delete these lines
	if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
		die ('Please do not load this page directly. Thanks!');

	if ( post_password_required() ) { ?>
		<h5>Comments</h5>
		<div class="comments">This post is password protected. Enter the password to view comments.</p>
	<?php
		return;
	}
?>

		<div id="comments">
		<h5>Comments</h5>
<?php if ($comments) : ?>
<?php foreach ($comments as $comment) : ?>

			<div  class="comment" id="comment-<?php comment_ID() ?>">
			<?php comment_text() ?>
			</div>
			<h4>by <?php comment_author_link() ?> @ <a href="#comment-<?php comment_ID() ?>" title=""><?php comment_date('d M Y, h:i a') ?></a> <?php edit_comment_link('Edit Comment','',''); ?></h4>
<?php if ($comment->comment_approved == '0') : ?>
			<em><?php _e('Your comment is awaiting moderation.'); ?></em>
<?php endif; ?>
<?php endforeach; /* end for each comment */ ?>
<?php else : // this is displayed if there are no comments so far ?>
<?php if ('open' == $post->comment_status) : ?>
		<div class="comment">There are currently no comments.</div>
<?php else : // comments are closed ?>
		<div class="comment">Comments are closed.</div>
<?php endif; ?>
<?php endif; ?>

		</div>

		<div id="form">
<?php if ('open' == $post->comment_status) : ?>
		<h5 id="respond">Leave a Reply</h5>
<?php if ( get_option('comment_registration') && !$user_ID ) : ?>
		<div class="comment">You must be <a href="<?php echo get_option('siteurl'); ?>/wp-login.php?redirect_to=<?php the_permalink(); ?>">logged in</a> to post a comment.</div>
<?php else : ?>
			<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">
<?php if ( $user_ID ) : ?>
				<p>Logged in as <a href="<?php echo get_option('siteurl'); ?>/wp-admin/profile.php"><?php echo $user_identity; ?></a>. <a href="<?php echo get_option('siteurl'); ?>/wp-login.php?action=logout" title="Log out of this account">Logout.</a></p>
<?php else : ?>
				<input type="text" name="author" id="author" size="30" value="<?php if($comment_author == "") echo 'Name'; else echo $comment_author; ?>" onblur="if (this.value == '') {this.value = 'Name';}"  onfocus="if (this.value == 'Name') {this.value = '';}" tabindex="1" />

<?php endif; ?>
				<br /><textarea name="comment" id="comment" cols="30" rows="3" tabindex="4"></textarea>
				<br /><input name="submit" type="submit" id="submit" tabindex="5" value="Add Comment" />
				<?php comment_id_fields(); ?>
			<?php do_action('comment_form', $post->ID); ?></form>
<?php endif; // If registration required and not logged in ?>
<?php endif; // if you delete this the sky will fall on your head ?>
