Hello,
I’m sorry to hear that you’re encountering issues with your sitemap. The “Incorrect HTTP header content-type” error can indeed cause the “Couldn’t fetch” status in the Google Search Console.
To resolve this issue, you can follow these steps:
-
Flush Permalinks: Navigate to your WordPress Dashboard → Settings → Permalinks and click the Save Changes button without making any changes to the permalink settings. This will flush your permalinks.
-
Flush Sitemap Settings: Go to Rank Math SEO → Sitemap Settings inside your WordPress admin area. Change the value in the Links Per Sitemap and click the Save Changes button at the bottom of the page.
If you’ve already tried these steps and are still facing issues, please let us know, and we’ll be happy to assist you further.
Thank you for bringing this to our attention!
