Issue with being able to display comments on pages.

Hello, I found this post on google trying to figure out how to add comments to my pages.

https://gvectors.com/forum/how-to-and-troubleshooting/how-can-i-insert-wpdiscuz-into-a-page-as-a-standalone-comment-wall-i-e-detached-from-any-wp-post/#post-1279

I'm using the Extra Theme by Elegant. You can see here that I have enabled comments on pages... 

I tried adding the function shortcode and adding it to my page but that didn't work. I also tried putting the tag <?php comments_template() ?> into my single.php file as well and that didn't work, as well as...

if(file_exists(ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php')){
      include_once ABSPATH . 'wp-content/plugins/wpdiscuz/templates/comment/comment-form.php';
}

Is there anything else I can do to get this to work? I really need a solution. Thanks!
