I have been trying to set my sitemap to Google Search Console, but it gives error “Sitemap is HTML”, even when it is clearly not. I have tried many times over long period of time. The sitemap is located: https://renkaat.copart.fi/sitemap.xml
FAQ only stated that this problem occurs time to time and suggested to wait some time and try again. I could not found any other topic here with same problem.
I have tried to change settings so that it does not generate html at all, it does not try compress it and removed style sheet. Content type header seems to be text/xml; charset=utf-8 and this should be ok.
We are using Woocommerce and we have some other plugins as well. We disabled Yoast SEO plugins sitemap creation, there should not be any other plugin to generate it.
What could be the problem here?
