Disable WordPress sitemaps

Since WordPress 5.5, core ships built-in XML sitemaps. That can overlap with SEO plugins that already generate sitemaps, or add work you do not need.

When to disable

• An SEO plugin already manages sitemaps (Yoast, Rank Math, All in One SEO, and similar).
• You want one sitemap source only.
• You prefer an external sitemap workflow.

Disable with Security Ninja Pro

1. Go to Security Ninja → Fixes.
2. Enable the option to disable WP sitemaps.
3. Confirm https://yoursite.com/wp-sitemap.xml no longer serves the core sitemap.

Manual method

Add this to a child theme functions.php or a small custom plugin:

add_filter( 'wp_sitemaps_enabled', '__return_false' );
