Then remove the below mentioned code that you will find on content.php page line 64 to 68 and content-search.php page line 45 to 49.
<?php if ( comments_open() ) { ?>
<div class="comments">
<?php comments_popup_link( __('No Comments', 'newscard'), __('1 Comment', 'newscard'), __('% Comments', 'newscard'), '', __('Comments Off', 'newscard') ); ?>
</div><!-- .comments -->
<?php } ?>
Note: we recommend you to customize the code after making a child theme so that you won’t loose any customized code when you update the new to a new version in future.
Thanks
