Error When Clicking "Get Access Code"

I use this plugin on a couple of blogs, but my most recent install won’t work. I’ve even tried deleting and reinstalling the plugin.

When I click “Get Access Code” it takes me to a Google error page. Here’s what it says:

400. That’s an error.

Error: invalid_request

Missing required parameter: client_id
