Google Maps JavaScript API v3 - ERROR

[Jesse]

Today two of my sites came up with this error:

The provided key is not a valid Google API Key, or it is not
authorized for the Google Maps Javascript API v3 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/tutorial.html#Obtaining_Key

Seems strange that two separate site on different servers are
experiencing this error. None of the code has been touched in between
times.

It this just a temporary glitch on Google's end? What can I do to
prevent this popup from happening?

Have you considered what the error message is saying? If you are specifying a key, is it a valid key that is authorized for that particular site?

This morning I am suddenly getting this exact same error.  The message says:

The provided key is not a valid Google API Key, or it is not authorized for the Google Maps Javascript API v3 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/tutorial.html#Obtaining_Key

Like the previous poster, I haven't changed anything but suddenly this morning I am getting this error.  I did read the recommended guide to double check and everything is still set up correctly and in my console they key is still set up and correct for simple API web access.

Please contact me directly if you need more specific details to debug this problem.

thanks.
