How to show more than one post excerpt on my blog page?

Btw, of course I already set Settings / Reading to show 5 posts, but my blog completely ignores it..

and possibly

a loop has the general structure:

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

//output section

endwhile;
else : echo 'no posts';
endif; ?>

Hi, I already tried adding that, just before the end of </article as I’ve seen adviced by many here, no luck.

Don’t know if anyone wants to look at it, but here’s the code for index.php

<?php
get_header();
the_post();
?>

  <div id="content">

         <img class="tape" src="<?php echo get_template_directory_uri(); ?>/img/tape.png" alt="" />
        <div id="breadcrumb"><span xmlns:v="https://rdf.data-vocabulary.org/#"><span typeof="v:Breadcrumb"><span class="breadcrumb_last" property="v:title"><?php the_breadcrumb(); ?></span></span></span></div>

        <div class="topbillede"><?php echo rwmb_meta( 'surfsmart_topbillede' ); ?></div>

        <article style="margin-top:40px">
		<h1><?php the_title(); ?></h1> 

            <?php the_content(); ?>
<br>
<?php the_author(); ?> - <?php the_date(); ?> 

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

//output section

endwhile;
else : echo 'no posts';
endif; ?>

        </article>

        <div class="bundbillede"><?php echo rwmb_meta( 'surfsmart_bundbillede' ); ?></div>
        <p class="deldette">Del siden</p>
	<div style='margin-top:20px;'><?php the_ratings(); ?></div>
        <div class="sharethis">
            <div class="addthis_toolbox addthis_default_style" style="float:left">
                <a id="facebookLike" class="addthis_button_facebook"></a>
                <a class="addthis_button_linkedin"></a>
                <a class="addthis_button_tweet"></a>
                <a id="plusone" class="addthis_button_google_plusone"></a>
            </div>
        </div>
        <script type="text/javascript">
            var facebookLike = document.getElementById("facebookLike");facebookLike.setAttribute("fb:like:layout", "button_count");facebookLike.setAttribute("fb:like:show_faces", "false");facebookLike.setAttribute("fb:like:width", "100");facebookLike.setAttribute("fb:like:action", "share");facebookLike.setAttribute("fb:like:font", "tahoma");facebookLike.setAttribute("fb:like:colorscheme", "light");var plusone = document.getElementById("plusone");plusone.setAttribute("g:plusone:size", "medium");plusone.setAttribute("g:plusone:lang", "it-IT");plusone.setAttribute("g:plusone:width", "100");
        </script>

        <div class="priserne"><?php echo rwmb_meta( 'surfsmart_price' ); ?></div>

<div style='margin-left:400px;'><?php posts_nav_link( $sep, $prelabel, $nextlabel ); ?></div>    

</div>
</div> <!-- end pagebox -->
<?php get_sidebar(); ?>
<div style="clear:both"></div>
<?php get_footer(); ?>

Is there anything obvious that I need to add to index.php to make WP show more than one post? Right now I don’t even care about excerpts, I just want it to show more than one post :S

I found a solution, however it’s a pretty ‘dirty’ solution and not the one I wanted to use to solve this problem.

I basically created a new template and hardcoded it, now at least it does what it’s supposed to.

Closing.
