Google Maps API issue sensorfalse causing errors

Hi,

I'm looking to buy the Soundess theme but am currently testing it out for functionality.

At the moment I'm getting the following error whenever anyone visits the site logged out:

The Google Maps API server rejected your request. The "sensor" parameter specified in the request must be set to either "true" or "false".

I can't see an easy way of fixing this and have tried a few solutions with no luck.

Can you let me know how I can resolve the issue? Also, the map doesn't appear on the contact page when logged out.

Logged in, it is fine and the maps displays too.

I look forward to your support.
Ashley
