Thank you for your query, and we are so sorry about the trouble this must have caused.
The default sitemap generated by WordPress is typically found at example.com/wp-sitemap.xml.
However, when you install and activate Rank Math, it generates its sitemap at example.com/sitemap_index.xml.
To ensure a smooth transition and avoid conflicts, Rank Math automatically creates a 301 redirect from the default WordPress sitemap URL to the new Rank Math sitemap URL.
The issue you are facing could be due to a few reasons:
1 . A conflict with another plugin or your current theme.
2 . A misconfiguration in your server settings.
3 . The presence of another active plugin that is also generating a sitemap.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), lets check for a conflict with one of the plugins or the theme you are using.
Only the site admin would know and your users won’t be affected by this troubleshooting.
If the issue persists, please edit the first post on this ticket and include your WordPress & FTP 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: https://wordpress.org/plugins/temporary-login-without-password/
thank you for your message.
Actually that should have worked as temporary login, but I guess there went something wrong.
I send you the password in the sensitive section.
I tried to login to the WordPress admin with the login details you provided and but always got the error “Incorrect username or password”. Would you please check the login details and provide us with the correct one.
sorry super strange, that the logins doesn’t work.
I followed your advice and madee a temproary login for you, which I added to the sensitive data field.
