The steps below outline how comments can be turned off in WordPress.
Disabling Comments on Future Posts
In the WordPress admin go to Settings > Discussion. Uncheck “Allow people to submit comments on new posts“. This will ensure that comments are disabled for all future posts.
Disabling Comments for Existing Posts
Changing the above setting will not affect existing posts. To disable commenting for existing posts, go to Posts and select individual posts to update or select all posts by clicking the checkbox in the header. After selecting your posts, choose Edit from the Bulk Actions dropdown, and click Apply. In the bulk editor, select Do not allow from the Comments dropdown and click on Update.
Show/Hide comments from the theme setting
The Kadence Theme also provides a way to show/hide the comments in
Appearance > Customize > Posts/Pages Layout > Single Post Layout.
Using a PHP Code Snippet
You can disable comments via a PHP code snippet. This will not only close comments and pingbacks but also hide any existing comments on the front-end.
// Close comments on the front-end
add_filter('comments_open', '__return_false', 20, 2);
// Close pings on the front-end
add_filter('pings_open', '__return_false', 20, 2);
// Hide existing comments
add_filter('comments_array', '__return_empty_array', 10, 2);Using a Plugin
Another option is to use a plugin that disables comments throughout the site. Disable Comments is a good option.
