Hello,
We apologize for the issue you are facing with the disappearance of your "post types" sitemaps. It sounds frustrating, and we appreciate you bringing this to our attention.
Since you’ve already tried the solutions from our blog regarding 404 errors, here are a few additional steps you can take to troubleshoot this issue:
-
Flush Permalinks: Sometimes, simply flushing the permalinks can resolve sitemap issues. You can do this by going to Settings → Permalinks in your WordPress admin area and clicking the “Save Changes” button without making any changes.

-
Check Sitemap Settings: Ensure that the post types you want to include in your sitemap are enabled in the Rank Math settings. Go to Rank Math SEO → Sitemap Settings and verify that the relevant post types are checked.
-
Plugin Conflicts: There might be a conflict with another plugin. You can use the Health Check plugin to identify any potential conflicts.
-
Caching Issues: If you have caching plugins enabled, try clearing the cache or temporarily disabling them to see if that resolves the issue.
-
Robots.txt File: Check your robots.txt file to ensure that it is not blocking access to your sitemaps. You can find this under Rank Math SEO → General Settings → robots.txt.
If these steps do not resolve the issue, please reply to this ticket with your site URL so that we can assist you further. A human agent from our support team will take over and provide more specific guidance.
Thank you for your patience, and we look forward to helping you resolve this issue!

Hello,
Could you please apply the following filter to your site to disable the transients cache for the sitemap and see if that works for you:
add_filter( 'rank_math/sitemap/enable_caching', '__return_false');
Here’s how you can add a filter/hook to your WordPress site:

If the issue persists, 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:
https://wordpress.org/plugins/temporary-login-without-password/
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):

Let us know how it goes. Looking forward to helping you.
Thank you.

I have updated the sensitive data as requested. Can you please check further?
Thank you for the support
Hello,
We deeply apologize for the unexpected delay in response.
For further troubleshooting, we might need the FTP logins of your website.
If you’re not sure about your site’s FTP logins, you can get in touch with your hosting provider and then share the logins in the sensitive data section.
However, we can see you’re currently using the Rank Math Business subscription on your websites, but the account you have used to open this ticket is the Rank Math free version.
Please search and forward a receipt from FastSpring.com so we can locate your account and verify it.
Looking forward to helping you.
Thank you.
