How to remove "leave a comment" on all the pages

Hello,
To make the changes please create or download child theme from http://catchthemes.com/blog/create-child-theme-wordpress/
then copy the content-sidebar-yourpagelayout.php . (yourpagelayout is the layout of your website, if you have sidebar to the right use content-sidebar-right.php or if you have it on the left use content-sidebar-left.php and so on)
Then paste the php file on the child theme’s root directory, finally open the file and find and replace <?php comments_template(); ?> to

<?php
     $comments_args = array(
      'title_reply'=>''
 );
comment_form($comments_args);
?>

If you have any queries and want a swift response please visit the themes official forum
