sitemap broken

that is all I get

this on effectivehairremoval.net

Error loading stylesheet: A network error occurred loading an XSLT stylesheet:https://www.effectivehairremoval.net/wp-content/plugins/google-sitemap-generator/sitemap.xsl

I checked and I do have the sitemap.xml and can view it properly.

First time this ever happened
