Sitemap is not updating

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience caused.

Please add this filter in the theme’s functions.php file:

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

Here is a guide you can follow to add the filter:

Once done, clear your website cache and check the sitemap.

Let us know if the issue persists.

We are here to assist you.

Hello,

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
