Looks like google released some change.

Caused our telematics app to lose maps on production. It only took an hour reading through zero release documentation on google maps documentation and debugging to pin it down....

Depending on what you are doing. Adding the version number to your import might solve your problem. like so https://maps.googleapis.com/maps/api/js?key=[YourAPIKey]&v=3.XY

"v=3" will also work. A this point I'm assuming if you don't specify a version you are always on latest which may not mean stable.

				if ($googleStaticMapKey != "")

				{

					$key = "&key=$googleStaticMapKey";

				}

				else if ($googlekey != "")

				{

					$key = "&key=$googlekey";

				}

				if ($googleStaticMapKey != "")

				{

					$key = "&key=$googleStaticMapKey&v=3";

				}

				else if ($googlekey != "")

				{

					$key = "&key=$googlekey&v=3";

				}
