Only one post is showing

Hello fellow wordpressers!

I’m working on a new theme and somehow only one blogpost is showing. I have no widgets or plugins installed so no need to ask me to deactivate them.

here’s the post code

<div id="blogg_"
    <?php if (have_posts()) : ?>
	<?php while (have_posts()) : the_post(); ?>

        <div <?php post_class() ?>>
        	<h2><a>"><?php the_title(); ?></a></h2>

				<?php if ( has_post_thumbnail() ) : ?>
				<div class"post_thumb">
            		<a>"><?php the_post_thumbnail(); ?></a>
            	</div><!-- post_thumb -->
            	<?php endif; ?>

                <?php the_content(''); ?>
					<ul class="meta"> 

<li><?php the_time('F jS, Y') ?></li>
<li>Posted in <?php the_category(', ') ?></li>
<li><?php comment_number('No Comments','1 Comment','% Comments'); ?></li>
					<!-- meta -->
	</div><!-- post_class -->

                <?php endwhile; ?>

            	<div class="pagination">

<ul>
                    	<li class="order"><?php next_post_link('Older') ?>
                        <li class="newer"><?php previous_post_link('Newer') ?>
                    </ul>
                </div> <!-- pagination -->

                <?php else : ?>

                	<h2>Nothing Found</h2>
                    <p>What you're looking for does not excist.</p>
                    <p>Return to <a>">Homepage</a></p>

                <?php endif; ?>

</div><!-- blogg_ -->

I followed a new tutorial, and somehow somewhere things went wrong. Any ideas?
