How to Remove Comments From Blog Posts
There are several ways to disable comments on your WordPress site: site-wide, by post type, or post by post.
To disable comments on your entire site you can use the Disable Comments plugin to get the job done.
By Post Type
To disable comments based on the post type (posts, custom, etc), we recommend the following plugin: No Page Comment.
Post by Post
To disable comments on a single post, navigate to the post edit screen within the admin and uncheck the Allow Comments setting in the Discussion meta box as shown in the screenshot below. Doing this will also hide the comment icon in the post meta on archive pages. For step-by-step continue with the screenshots below.
1. Click "Edit Post"
2. Click on "Screen Options", "Discussion" and "Comments"
3. Once these are checked, scroll down to the bottom of your page and you will now see Discussion.
4. Uncheck both "Allow Comments" and "Allow trackbacks and pingbacks on this page"
5. Congratulations, now your blog does not allow comments!
