I\'m having a problem with getting my Google Maps API key to work. I originally had the problem when trying to access http://dev.domain.com using a key generated for http://
I was having the same problem and it turned that i was doing 2 calls to the http://www.google.com/jsapi url. The first one for adsense (without the key parameter) and then the second one for google maps with the key. Pretty stupid mistake but the result is that the although you put the key on the second call it doesn't use it.
