Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
It looks like the permalink structure on your website is set to plain which is why the URL is not changed in Sitemap settings.
To change this, you need to set the permalink structure to Post name at WordPress settings > Permalinks
Please note that changing the permalinks on a live, indexed, and established site may result in a serious loss of traffic.
Hope that helps.
Thank you.
It has been changed, but it shows 404 Not found. Do I need to change anything?
Hello,
Can you please follow these steps?
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:

That should fix the issue. Please let me know if that does not. We are here to assist.
