 * Using the twenty ten theme, I get a 500.0 error, something about fast-cgi, after
   installing this plug-in. I have tried to install it though both the interface
   and manually.
 * Will this work on IIS?
 * Here is a screen shot of the error:

 * I would really like to get this working as my page takes 3 seconds to load. Thank
   you.
