Brian,
The code-fix we provided above is *not* included in the latest release. It's not something we'd set permanently for everyone, but we could add an option to enable a 'fallback mode' for it to help fix your site and any others that may run into the same problem.
However, the "Application Not Configured" message makes me think the above code-change isn't the problem. If you're getting that message, communication with Google seems to be working, but something in the Google app is probably not setup right.
Here's my suggested path forward:
* Implement the code change above and see if that fixes things. If so, let us know and we can add that option to the next release. That should fix you up going forward.
* If not, leave the code change in place and double-check your Google Application settings. If everything looks right, try creating one more Google App following
our Google App Setup Guide
step by step.
** If the 'new' key works, that indicates there is an issue with some setting in your original app. Find it and fix it.
** If the 'new' app still fails (ideally in the same way), let us know and we can FTP into your site to add more debug code and narrow down what else may be happening.
Thanks,
Alex
