Had the same error
rcpig_grid.min.js:4 Uncaught TypeError: Modernizr.prefixed is not a function
at a.fn.init.a.fn.rcpig_grid (rcpig_grid.min.js:4)

Seems to be a conflict of some sort, it works on other themes but not the current theme being used by our site. rcpig_grid.min.js line 4 seems to be the culprit. i’ll try and dig around, hopefully i can come up with a solution.
