RMRH_VALUES is not defined

Hello,
I’m getting an odd Javascript error in Chrome’s console.

Uncaught ReferenceError: RMRH_VALUES is not defined

Any ideas?

Here’s a link to the site using it:
http://chriswarrenphoto.com/category/blog/

The only post that uses the more tags is the “Longs | Family 2012”.

Any help is much appreciated.
