 * Did you follow these instructions exactly: [http://docs.simplecalendar.io/google-api-key/](http://docs.simplecalendar.io/google-api-key/)
 * It sounds like you might have added a whitelist URL or something when you created
   the API key?
 * If not then try going through this to rule out any other possible conflicts first:
   [http://docs.simplecalendar.io/troubleshooting-theme-plugin-widget-conflicts/](http://docs.simplecalendar.io/troubleshooting-theme-plugin-widget-conflicts/)
 * let me know about those 2 things and then we can go from there.
