1.But I am not getting the path how to look at the Java Script Console to see the problem description.
2.I got the google API key which is configured in the dynamic system settings 3. While viewing the preview of the section the map is shown/visible for a sec and then getting vanished followed by that error message as stated above. If it is the problem with API key configured even the 1 second display should not work. not sure about the exact problem but trying to nail down options.
