Modernizr 1.6ish: miniModernizr for Isotope detected.

Modernizr 1.6ish: miniModernizr for Isotope detected. This version is known to cause issues with async JavaScript loaders. Please upgrade to at least 2.6: http://modernizr.com/

from generated script
rocket.js

I get this error quite a lot when using this theme and rocketloader. Does anyone know how to fix this? How do we upgrade modernizer? I don’t see where it wp_enqued – so we can de_enque and re-register an updated version.

Is there another fix perhaps?
