We use a browser feature called "websockets" to display backtest results. If you never get backtest results that implies that your websocket isn't connecting. That can be because of an old browser version, a firewall between you and Quantopian, a interfering browser plugin, or very aggressive browser security settings. Given that it worked for you for a while, but then stopped working, that might help in the troubleshooting. Were you on the same browser on both days? Same computer? Same network?
I suggest you troubleshoot it from that angle. If it doesn't work drop us an email at [email protected] for more troubleshooting.
EDIT: I looked at the database, and I can see that you're getting some exceptions today, and some completed algorithms. The most recent successful one was a full backtest kicked off at 3:57PM EDT, followed by 3 "builds" that had exceptions.
