Preventing Rank Math from Flushing W3 Total Cache

In Rank Math, we use the w3tc_pgcache_flush function to flush the cache when a post is updated or added to the site. If you don’t want Rank Math to flush the cache, then follow the steps we’ve discussed below.

1 Navigate to the Theme File Editor

First, navigate to Appearance > Theme File Editor (for a Classic Theme) inside your WordPress admin area.

Please disable the Sitemap cache by adding the following filter code to your theme’s functions.php file to prevent the plugin from running this function. You can further refer to our dedicated tutorial on how to add a filter/hook to your website.

add_filter( 'rank_math/sitemap/enable_caching', '__return_false');

Navigate to the functions.php file and add the code snippet, as shown below.
