Error loading stylesheet: A network error occurred loading an XSLT stylesheet:

I am getting the above error in Firefox 32.0, in Chrome Version 37.0.2062.120 I get a blank page but show page source displays the XML file (it is a schema).

The details are that this is a stylesheet that I am developing and when I reference it locally, it is working as expected. Adding the reference to the schema from the website copy causes this error.

The sylesheet is located http://ift.tt/1quoRWf

An examples of the source schema files are here: http://ift.tt/1uZt6PN

They do not have the reference to the style sheet (yet) but adding:

<?xml-stylesheet type="text/xsl" href="http://ift.tt/1quoRWf"?> 

to one of those schemas should display the problem.

I will add that the website is hosted by github and the full URL to the stylesheet is http://ift.tt/1quoURL But even using that I get an 'unknown error'.

I know that GitHub redirects www.mlhim.org to mlhim.org But changing the reference to not use the 'www' also gives me a network error.
