Problem to create a loop

Hello!

I have a following problem when I’m trying to create a loop with all previous posts at the bottom of each post.

Actually, I would like that the loop has the same presentation/design as it apprears on the home page of my site. (my Theme is “OBLIQUE”.)

I tried to make a copy of the design of the homepage. So, I copied a part of the code from the document index.php into the document single.php , like this:

<?php if ( have_posts() ) : ?>
<?php /* Start the Loop */ ?>
<div id=”ob-grid” class=”grid-layout”>
<?php while ( have_posts() ) : the_post(); ?>
<?php
/* Include the Post-Format-specific template for the content.
If you want to override this in a child theme, then include a file
called content-___.php (where ___ is the Post Format name) and that will be used instead./

get_template_part( ‘content’, get_post_format() );
?>

<?php endwhile; ?>
</div>

<?php the_posts_navigation(); ?>

<?php else : ?>

<?php get_template_part( ‘content’, ‘none’ ); ?>

<?php endif; ?>

I put this code just before this:
</main><!– #main –>
</div><!– #primary –>

But the only result that I have is one link to the current post. The loop with all the post does not apprear.

Could you help me please? Where is the mistake?
