I'm getting challenge with a plug-set for word press that has hardly any documentation about this. I'm focusing on http://goo.gl/fgVM and anywhere the marker is, it's NO ACTION on click, what is strange is the fact that a appear seems basically install this plug-in on another theme/install. I'm wondering if anybody with Google map API understanding can easily see if there's anything conflicting?

There's a JS error: Uncaught ReferenceError: initialize isn't defined
