Hi there,
fitst you need to find your layout that you are using currently then you need to place this following code after the comments_template() function.
`<nav class=”nav-single”>
<h5 class=”assistive-text”><?php _e( ‘Post navigation’, ‘encounters-lite’ ); ?></h5>
<?php previous_post_link(_x(‘Previous Post: %link’,’Previous Post Navigation’, ‘encounters-lite’),’ %title’); ?><br />
<?php next_post_link(_x(‘Next Post: %link’,’Next Post Navigation’,’encounters-lite’),’ %title’); ?>
</nav><!– .nav-single –>`
Let’s say you are using blog-right then you need to customize blog-right.php template .
Note: Please proceed this steps if you are technically sound oN wordpress, otherwise you will face some fatal error.
And also please child theme to customize the parent template.
Thanks
