Hello,

Sorry but the comments are not enabled in pages by default. To add them follow these steps:
1-please go to file page.php and find this line:

<?php endif; ?>
<?php get_footer(); ?>

Replace with these:

<?php endif; ?>
<?php comments_template( '/includes/view/blog/comments.php');  ?>
<?php get_footer(); ?>

2-Add this code into your custom css box:

.page #comments {  width: 80%; padding-left: 16%; border-top: none;}
.page div#respond {  padding-top: 11% !important; padding-left: 16%; padding-bottom: 60px;}
.page #respond textarea { width: 80%; padding-left: 16%;}

Save!

Best regards!
