2.7 Theme Break – All posts display

All posts show no matter which post you chose to see. Click on the post at the top right of the page to see the results (or chose “blog” from the left navigation at https://www.fullscalearchitecture.com/press

The problem is theme-based as changing the theme fixes the problem. Code is below:

<?php get_header(); ?>
<div id="wrap">

<?php include(TEMPLATEPATH."/left.php");?>

<?php get_sidebar(); ?>

<div id="content">
	<?php if (have_posts()) :?>
		<?php $postCount=0; ?>
		<?php while (have_posts()) : the_post();?>
			<?php $postCount++;?>
            <?php if (get_post_meta($post->ID, 'header image', true)) { ?>
           <img src="<?php echo get_post_meta($post->ID, 'header image', true); ?>" />
 <?php } else { ?>
 <?php } ?>
<?php if (is_home()) { ?>
           <h2 class="entrytitle"><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
           <h3 class="entrydate"><?php the_time('F jS, Y') ?>, By <?php the_author() ?></h3>
 <?php } elseif (is_single()) { ?>
 <h2 class="entrytitle"><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
           <h3 class="entrydate"><?php the_time('F jS, Y') ?>, By <?php the_author() ?></h3>
 <?php } elseif (is_page('about')) { ?>

 <?php } else { ?>
			<h2 class="entrytitle"><?php the_title(); ?></h2>
 <?php } ?>

<?php the_content('Read More &raquo;'); ?>

	<?php endwhile; ?>
	<div class="navigation">
	<div class="nextposts"><?php next_posts_link('[OLDER]') ?></div>
	<div class="previousposts"><?php previous_posts_link('[NEWER]') ?></div>
		</div>

	<?php else : ?>
<div class="not_found">

</div>

<?php include(TEMPLATEPATH."/right.php");?>
