Thread:Project:Support desk/Problem getting Google to find sitemap

I just created a sitemap at en.sturmkrieg.com/sitemap.xml and added it with Google Webmaster Tools, but it gets a 404 error. I tried adding two lines to .htaccess since the problem could be getting redirected by the short url, but it didn't work; I could have just written it wrong.

RewriteCond %{REQUEST_URI} ^/sitemap.xml$ RewriteRule ^.*$ - [L]

I based it off of the code here for fixing the stats page of Dreamhost wikis, since it looks like it's fixing the problem of the URL being treated as a wiki page.

Did I guess the problem right? How would I go about fixing it?

en.sturmkrieg.com/robots.txt seems to be fine.
