Custom sitemap and transient cache

  • Resolved Massimo
    Rank Math free

    Hi, when I add a custom sitemap with filter rank_math/sitemap/index I see that is added only if I add add_filter( 'rank_math/sitemap/enable_caching', '__return_false');. This is as default or I need to clean a specific transient?

    Best regards

  • Hello,

    Thank you for contacting Rank Math and bringing your concern to our attention.

    Yes, to clear the custom sitemap cache, you’ll have to execute the \RankMath\Sitemap\Cache::invalidate_storage( ‘amp’ ); on save_post hook.

    However, if you’re not sure how to do it, we would recommend you disable the sitemap cache completely by adding the filter you have shared.

    Hope that helps.

    Thank you.

    Hi Reinelle, my problem isn’t clean in save_post but add a new sitemap without add the filter to disable cache. I attach my code, maybe I forgot something?

     * Add new sitemap
    add_filter( 'rank_math/sitemap/index', function( $xml ) {
        $midnight = strtotime("today 00:00");
    	$xml .= '
    			<loc>'. get_site_url() . '/test-sitemap.xml</loc>
    			<lastmod>' . date('c', $midnight) . '</lastmod>
        return $xml;
    }, 11 );
     * Add link to sitemap (I've modded this filter)
    add_filter( 'rank_math/sitemap/soci/content', function() {
       return '<url>

    Best regards


    If you do not wish to use that filter code to disable file caching of sitemaps, please make sure that your plugins aren’t caching the sitemaps. You may refer to the steps below to do just that:

    1. Flush the Sitemap cache by following this video screencast:

    2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

    Let us know if that works for you.

    Looking forward to helping you. Thank you.

    Thanks Jeremy, that work

    Best regards
