Map not loading

Firstly let me start by saying the extension looks excellent and is far better than the other map extensions I have tried.
I do have a problem though.
On the frontend of my website the map does not load. There is just a spinning wheel.
I checked with "inspect element" on Chrome and
Uncaught ReferenceError: google is not defined
was displayed.
I have checked the webpage on Firefox and IE and the map fails to load on these too.
Any help would be appreciated

Hi,

and thanks for taking the time to look.

Thanks,I will investigate.

Thanks,
The issue was caused by a plug-in.

It is called "Scripts Down"

Can't remember installing it, but the map works fine now the plug in has been disabled
