UPDATE: Yoast SEO compatibility issue with WP Super cache
Content-type returned by sitemap URL is content-type:text/html; charset=”UTF-8″ which is wrong.
The problem is that Yoast’s plugin needs to tell Supercache that the URL is a sitemap.
As a temporary fix, you can add the following to the Add here strings (not a filename) that forces a page not to be cached in ADVANCED setting section.
sitemap(_index)?\.xml(\.gz)? ([a-z0-9_\-]+)?sitemap\.xsl [a-z0-9_\-]+-sitemap([0-9]+)?\.xml(\.gz)?
