I was getting a persistent javascript error in Internet Explorer 8 (I know, but I have to test against it). The error (function expected) referenced line 316 in customizr/inc/js/holder.js
Replacing the version 1.9 of holder.js with version 2.0 from this Git site fixed the error:

Hope this is helpful.
