I’m having the exact same problem. I’ve had issues with the Twitter feed on my website before, but it usually resolves itself within a few hours. This has gone on for at least a couple of days. I see that Twitter has posted some stuff about some new “REST API v1.1” but of course never bothered to explain what any of that means. So I don’t know if that is related to this problem or not. Can someone respond to this issue in plain English, please?
