Removing the comments section from wordpress pages
This is a little more work. You need to select
Appearance >> Editor
Then under your theme select the page template which is normally called Page.php.
Once done, normally under or near this line of code <?php the_content(__( you will see line of code like this.
<?php// comments_template( '', true ); ?>
Simply delete that line and then save the template. Make sure you keep a note of the code in case you ever want to add it back in. Job done
