Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
If Rank Math doesn’t create a sitemap file or if you are getting a 404 error while trying to access your sitemap index, you may have to flush permalinks. Don’t be scared, it is fairly easy to do.
Simply head over to your WordPress admin area and go to Settings > Permalinks and hit the “Save Changes” button once even if you didn’t make any changes on the page.
This should fix the issue.
For configuring sitemap, please refer to our KB article here
I hope that helps. if not, please feel free to contact us again.
We’re here to help.
