Sitemap can be read, but has errors

Hello,

Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.

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:
https://rankmath.com/kb/exclude-sitemaps-from-caching/

3. Remove all previously submitted sitemaps from your GSC account and resubmit your main sitemap(sitemap_index.xml) and wait for Google to crawl the sitemap again.

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

Hello,

Can you please share your website URL with us so we can further check it on our end?

Looking forward to helping you.

Hello,

Your sitemap page is currently not loading properly as there seems to be a captcha form trying to hinder the generation of your sitemap:

Please check if there are other plugins or your current theme that might be adding this captcha. To determine that, please refer to this guide: https://rankmath.com/kb/check-plugin-conflicts/

Only the site admin would know and your users won’t be affected by this troubleshooting.

Looking forward to hearing back from you.

Hello,

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

Glad that everything has been sorted out. If you have any other questions in the future, know that we are here to help you.

Thank you.
