Google Maps API key not working

Question

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://domain.com, however I subsequently tried generating a key for http://dev.domain.com and it still didn't work.

I get the typical This web site needs a different Google Maps API key. A new key can be generated at http://code.google.com/apis/maps/. alert message when trying the site. Checking their FAQ and following it's instructions to alert(window.location.host) to check the domain returns dev.domain.com which looks correct (unless it's meant to have http:// at the start? In which case I don't see how I've done something wrong).

Both keys (dev.domain.com and domain.com) work correctly on localhost.

Does anyone have any ideas on what I can do to solve this or any further tests I can do to work it out?

Answer 1

I came across this question as I was just now beating my head against this same issue. I finally noticed that the code Google provided for linking to the API was different from what I'd been using. I replaced this

<script type="text/javascript" src="http://www.google.com/jsapi?key=___">
</script>
<script type="text/javascript">
    google.load("maps", "2.x", { "language": "en" });
</script>

with this

<script type="text/javascript" 
  src="http://maps.google.com/maps?file=api&v=2&sensor=false&key=___">
</script>

and the error went away.
