Guide @ https://developers.google.com/maps/documentation/javascript/tutorial#api_key The HTML of your site has this: <script type='text/javascript' src='http://maps.googleapis.com/maps/api/js?key=AIzaSyB_RNuKri7ldPdzPwA41IlMUjFTlR5rdo0&sensor=false&libraries=places&ver=4.1'></script> You need to update the `key` part. This may be update-able if you have a Google Maps plugin there, or it may be directly in the code of the header part. My guess is it's probably in some field in the admin ( Google Maps Plugin area or maybe your Theme has a GA Maps ID ).
