title: Google Map error: InvalidKeyOrUnauthorizedURLMapError
body: <p>I am developing in JavaScript/HTML/CSS an app that uses Google Maps. I am getting the following alert dialog box:</p>
  
  <p>"This page was unable to display a Google Maps element. The provided Google API key is invalid or this site is not authorized to use it. Error Code: InvalidKeyOrUnauthorizedURLMapError"</p>
  
  <p>The app <em>does</em> actually display the map element; the alert is not a problem except it should not appear at all. The map displays properly.</p>
  
  <p>I have gone in to the Google Developer's Console and, in the "Credentials" section, have "edited allowed referrers" to be mydomain.com/*</p>
  
  <p>I have also gone in to the Google Developer's Console in the APIs section and enabled 11 Google Maps APIs. </p>
