After one upgrade or another in the last week, GAD stopped working. When I begin the OAuth process, it loads into the correct Google page, I select the account and authorize it, but then when it posts back, for some reason it just shows a blank page. I have tried it in both Chrome and Firefox, with cookies cleared.
When I try and use the old authentication system, it returns an "Unknown Error".
I'm running GAD 2.0.3.
