Disqus is a good comment plugin system for WordPress which I use on all of my sites. Basically, Disqus plugin checks if comments are allowed on posts and pages in your wordpress site. If comments are allowed, Disqus will automatically insert the commenting system. If not, then it will not display the comments.
Login to your wordpress administration panel.
In your wordpress dashboard, click Pages.
Hover your mouse on the page you want to remove comments from and click Quick Edit.
On QUICK EDIT Panel, untick the “Allow Comments” and click Update.
- View your update page and comments are now disabled on this page. Perform similar procedures if you want to remove comments on other pages on your site.
