Category Page Only Displaying Latest Post Made In That Category

Hey there.

For some reason, my category page for a certain category is only displaying one post made in that category – the latest one. Even though I know there are 2 or 3 (WordPress Dashboard shows the stats for each category)

Try it out yourself.

The top bar are the categories, “Training” and “The Basics” have 2 or 3 articles each, yet only one shows up. Here’s my code.

<?php get_header(); ?>

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

<div class="post-container">
	<div class="post-header">
		<div class="post-avatar"></div>
		<div class="post-title">
			<?php the_title(); ?>
		</div>
		<div class="post-meta">
			Category: <?php the_category(', ') ?>.  Tags: <?php the_tags(__(''), ', ', ''); ?>.  <?php edit_post_link('Edit', ''); ?>
		</div>
		<div class="clear"></div>
	</div>
	<div class="post-content">
		<?php the_excerpt(); ?>
		<p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">Read More...</a></p>
	</div>
	<div class="clear"></div>
</div>
<div style="height:15px;width:100%;padding:0px;border-bottom:1px dashed #ccc;margin:0px 0px 15px 0px;"></div>

<?php endwhile; ?>

<?php else : ?>

<h2 class="center">Not Found</h2>
<p class="center">Sorry, but you are looking for something that isn't here.</p>

<?php endif; ?>

 </div>
 <!--/content -->

<?php get_sidebar(); ?>

<?php get_footer(); ?>

Help appreciated alot!
Thanks.
