This is probably a known bug, but I get the following error when trying to access any kind of google map (in an annoying javascript alert() ):

'Error: Google has disabled use of the Maps API for this application. The provided key is not a valid Google API Key, or it is not authorized for the Google Maps Javascript API v2 on this site. If you are the owner of this application, you can learn about obtaining a valid key here: http://code.google.com/apis/maps/documentation/javascript/v2/introduction.html#Obtaining_key'

Perhaps the API-key is still linked to the development-server instead of the live-server?
