Disable comments across your entire site or only for selected post types. This removes comment forms from the front end, hides comment-related menus and widgets in the dashboard, and disables pingbacks and trackbacks.
Delete comments in bulk with a simple cleanup tool. You can remove all comments at once or filter them by post type or comment status.
Manage links in comments by disabling the website field from the comment form for cleaner, safer comment submissions. Replace external links in comments with safe span tags so they no longer act as real, followable links.
<h3>Key Features</h3>
Disable comments 
– Disable comments globally or by post type 
– Hide all comment-related admin menus, dashboard widgets and settings 
– Disable pingbacks and trackbacks 
– Disable comments in RSS/Atom feeds
Delete comments 
– Delete all comments in WordPress at once 
– Delete comments by post type 
– Delete comments by comment status (spam, unapproved, trash)
Manage links in comments 
– Replace all external comment links with span tags via JavaScript, removing their SEO impact while keeping the text visible to users. 
– Remove the website/URL field from the comment form
All features can be enabled or disabled safely, and comment disabling does not remove existing comments unless you choose to delete them.
<h3>Why use this plugin?</h3>
WordPress still loads comment features even when you don’t use them, which can clutter your dashboard, expose unused functionality, and create unnecessary moderation work. This plugin gives you complete control over WordPress comments, whether you want to disable comments globally, bulk delete comments, or just manage them more efficiently.
<h3>Advanced Configuration</h3>
To prevent the plugin from replacing your theme’s comment template, define the following constant:
<pre><code>define('DISABLE_COMMENTS_REMOVE_COMMENTS_TEMPLATE', false);
</code></pre>
You can add this definition either to your <code>wp-config.php</code> file or to your theme’s <code>functions.php</code> file.
