Hi,
Since yesterday my sitemap page https://mysite.com/sitemap_index.xml is showing a 404 error and Google Console says there is a General HTTP error 404.
I updated WP yesterday, I am not sure if it has anything to do with that. Everything was okay on May 17th, the first error appeared on May 19.
Any ideas on what to do, I have already gone through deactivating plugins etc.
Thanks
