General configuration: enable the plugin, choose where to disable comments (everywhere or specific post types) and fine-tune what to remove, alongside the live status panel showing comments closed on the web, blocked via the REST API and pingbacks/X-Pingback removed.
Replai Comments gives you full control over WordPress comments and stops comment spam — from its own admin section.
Turn it on and choose where to disable comments:
While active, Replai Comments:
X-Pingback header, disables outgoing pingbacks and comment RSS/Atom feeds.Live status
A real-time panel tells you whether comments are actually open on the web and via the REST API, whether XML-RPC pingback and the X-Pingback header are removed, and — when comments are closed — why (by Replai Comments or by WordPress’s Discussion settings / the post itself). Re-check any time.
Cache-aware and editor-safe
When you save settings or delete comments, Replai Comments purges common page caches (WP Rocket, LiteSpeed, W3 Total Cache, WP Super Cache, WP Fastest Cache, SG Optimizer, Cache Enabler) so a cached page never keeps serving the comment form. It also leaves the block editor “Notes” comment type (WordPress 6.9+) untouched.
Bulk delete tool
Clean your database with one click: permanently delete all comments, or only pending, spam or pingbacks/trackbacks, processed in batches with live counters.
Everything runs on your own site, is fully reversible (turn the plugin off to bring comments back), and the whole admin is available in 7 languages (English, Spanish, Catalan, French, Italian, Portuguese and German) based on your site language.
For developers: define REPLAI_DC_KEEP_TEMPLATE (true) to keep your theme’s comment template, or REPLAI_DC_KEEP_DISCUSSION (true) to keep the Discussion settings page.
