Posts Not Showing in Rankmath Sitemap

Hello,

Thank you for contacting the support and we regret the inconvenience caused.

I checked the pages’ source and found that the URLs are loaded without the protocol. However, as an initial troubleshooting step please follow the below steps and see if that helps:
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:

3. Clear your website’s cache and check the sitemaps.

in case the issue persists, could you confirm if you’re using the WP Rocket caching plugin?

If yes, please head over to your WordPress admin area > WP Rocket > Settings > Cloudflare Settings, and disable the Relative Protocol option:

Once done, clear the website’s cache and see if the issue gets fixed.

Looking forward to hearing back from you.

Thank you.
