I’m using the Catch box theme and this worked for me.
Go to the editor
Click singlpost (single.php)
Find <nav id=”nav-single”>
<h3 class=”assistive-text”><?php _e( ‘Post navigation’, ‘catchbox’ ); ?></h3>
<span class=”nav-previous”><?php previous_post_link( ‘%link’, __( ‘<span class=”meta-nav”>←</span> Previous’, ‘catchbox’ ) ); ?></span>
<span class=”nav-next”><?php next_post_link( ‘%link’, __( ‘Next <span class=”meta-nav”>→</span>’, ‘catchbox’ ) ); ?></span>
</nav>
And comment it out by putting <!– at the beggining of the code and –> at the end
Update File
My knowledge of code is very limited I’m do not know alot about proper procedures so take my advice with a grain of salt
