Hi,
sorry for the delay to answer.
First of all, I have checked your code and there is a javascript error. That is because you load the map script but you don’t use it. If you don’t want to use it, remove the code where the library is loaded. It’s the line 265:
...src="http://maps.google.com/maps/api/js?key=YOUR_API_KEY"...
About the other problem with the subscription form, I’m going to find the problem. I will answer you asap.
Regards
