Edit the single.php file, you will have to use the following code below.
Changes includ changing the containing class just below get_header() and also adding get_sidebar() before the footer.
<?php
/**
* The template for displaying all single posts.
*
* @link https://developer.www.ads-software.com/themes/basics/template-hierarchy/#single-post
*
* @package Flation
*/
get_header(); ?>
<div class=”col-xs-12 col-sm-12 col-md-8″>
<div id=”primary” class=”content-wrapper”>
<main id=”main” class=”site-main” role=”main”>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( ‘template-parts/content’, ‘single’ ); ?>
<?php
the_post_navigation( array(
‘prev_text’ => ‘<i class=”glyphicon glyphicon-chevron-left” aria-hidden=”true”></i> %title’,
‘next_text’ => ‘%title <i class=”glyphicon glyphicon-chevron-right” aria-hidden=”true”></i>’
) );
?>
<?php
// If comments are open or we have at least one comment, load up the comment template.
if ( comments_open() || get_comments_number() ) :
comments_template();
endif;
?>
<?php endwhile; // End of the loop. ?>
</main><!– #main –>

<?php get_sidebar(); ?>
<?php get_footer(); ?>
