Switching from www to non-www, sitemap blank

Hello,

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

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 and browser’s cache and check the sitemaps to see if the issue gets fixed.

As for your second question, if you’ve already implemented the non-WWW variation, you can remove the WWW sitemaps from your Google Search Console account and only submit the index sitemap (/sitemap_index.xml) of the non-WWW variation.

As for the redirection, please try using the rules in this guide and see if it helps: https://rankmath.com/kb/how-to-redirect-www-urls-to-non-www/

Let us know how that goes.

Thank you.

Hello,

As you’ve submitted the new sitemaps to GSC, that sitemap would start to get crawled from now.

However, you can reach out to your web host and see if there’s any issue or solution they have to redirect the WWW version of the sitemaps to non-WWW.

Let us know how that goes.

Thank you.

Hello,

I checked and the sitemap is correctly redirecting to the preferred variation.

If there’s anything else that we can assist you with, please feel free to let us know.

Thank you.
