问题
I wish I could explain what's causing this issue. I've searched and simply have no idea. When I move this Foundations, Red, etc. framework between projects it tends to follow. Any advice would be useful.

回答1:
You're loading your customized Modernizr lib (with Hyphenator, which is causing the problem) in <head>, at a moment where <body> doesn't exist yet, hence the error.
An obvious solution would be to move the loading of the Modernizr lib to the bottom of your page (in or after <body>), although this suggests that doing that might cause some issues. If it does, try separating Hyphenator from the Modernizr lib and load it separately.
