shs_animate is not defined

Love the plugin. Great work 🙂

I recently noticed one of our network sites (WPMU) using SHS suddenly stopped working and console spits out Uncaught ReferenceError: shs_animate is not defined and repeats over and over again. I’ve tried disabling plugins and I don’t know what would be causing this problem.

Any insight / suggestion is greatly appreciated.
