404 Not Found Error with Comments on Page

Okay so here’s my site if you’d like to see the glitch first hand:

https://joehenry.frihost.net

On the “About” PAGE I have the comments enabled and working. The glitch is that after you fill out the form and submit the comment you get a 404 Not Found error. But then if you go back to the About page and refresh, your comment still shows up none-the-less.

Any ideas about what’s wrong are appreciated.

Here’s my page.php code:

<?php get_header(); ?>

<?php if (have_posts()) : while (have_posts()) : the_post();
	$date = $post->post_date;
	$date = my_date_format($date);
?>

<div class="sectionheader" id="post-<?php the_ID(); ?>"><a name="entry"></a>
	<div class="title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></div>
	<div class="commentsnum right"><a href="#comments"><?php comments_number(__('No Comments'), __('1 Comment'), __('% Comments')); ?></a></div>
	<div class="date"><?php echo $date; ?></div>
</div>

<div class="entry">
<?php wp_link_pages(array('before' => '<p><small><strong>Pages:</strong> ', 'after' => '</small></p>', 'next_or_number' => 'number')); ?>
<?php the_content('<p class="right">Read the rest of this page &raquo;</p>'); ?>
<?php wp_link_pages(array('before' => '<p><small><strong>Pages:</strong> ', 'after' => '</small></p>', 'next_or_number' => 'number')); ?>
</div>

<hr />

<p class="postmetadata"><small>
	<?php edit_post_link('Edit this entry &raquo;', '<p>', '</p>'); ?>
	<p>This page was posted on <?php the_time('l, F jS, Y') ?> at <?php the_time() ?>.</p>
<?php if ('open' == $post-> comment_status) { ?>	<p><a href="#comments">Leave a comment.</a></p><?php } else { ?>	<p>Comments are currently closed.</p><?php } ?>

</small></p>

<?php
comments_template();
endwhile;
endif; 

get_footer();
?>

I’m pretty sure that it’s not something in my comments.php code because the comments work fine on the post pages.

Thanks in advance and again, any help is really appreciated!
