category not showing in sitemap

Hello,

Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.

Please headover to Dashboard > Rank Math > Sitemap Settings > Taxonomies > Category :

And enable the “Include in sitemap” option.

After that flush the Sitemap cache by following this video screencast:

As for your sitemap.xml path not redirecting to sitemap_index.xml, could you please check if there’s any physical sitemap file in your FTP? It seems that the sitemap.xml is showing different content. If you find any, please delete it.

Let us know how that goes. Looking forward to helping you on this one.

Hello,

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress login 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.

Hello,

Please try updating the sensitive data section again.

If the issue still persists, please clear your website’s cache or try a different internet browser.

Looking forward to helping you.

Thank you.
