Network error loading XSLT stylesheet: xml-sitemap-xsl.php

Hello guys,

WordPress version: 3.4.1
WordPress SEO version: 1.3.2

I did this: Tried to generate a sitemap XML in many different ways, even excluding all post types and taxonomies

I expected the plugin to do this: Create the sitemap_xml file

Instead it did this: http://screencast.com/t/HbpGP8Nv

My servers run on nginx.
