This behavior is truly baffling. I am upgrading from v1.7 to v2.0.6 and it simply doesn't work. No errors are getting thrown, the code is loading correctly, yet nothing happens.

Before (works):

I am only loading a handful of the offered features that Modernizr provides. Just some basic CSS3 stuff and then IEPP. Features are the same from old to new. The class attribute is added to the html tag, but it is completely empty.

Any ideas?
