Any Idea why my Blog Section doesn't work?

hello,
can you please post the template source?
it should contain something like this:
https://codex.www.ads-software.com/The_Loop#Loop_Examples

I think this is it:

<?php get_header(); ?>

<div id=”mainContent”>
<div id=”primary”>
<div id=”content” role=”main”>

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

<?php else : ?>

<article id=”post-0″ class=”post no-results not-found”>
<header class=”entry-header”>
<h1 class=”entry-title”><?php _e( ‘Nothing Found’, ‘twentyeleven’ ); ?></h1>
</header><!– .entry-header –>

<div class=”entry-content”>
<p><?php _e( ‘Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post.’, ‘twentyeleven’ ); ?></p>
<?php get_search_form(); ?>
</div><!– .entry-content –>
</article><!– #post-0 –>

<?php endif; ?>

</div><!– #content –>
</div><!– #primary –>

</div><!–end#mainContent–>

<?php get_footer(); ?>

The Loop is missing. It should be placed in between
<?php if ( have_posts() ) : ?> and <?php else : ?>
