It was easy to see why there was no RSS feed or rendering happening when you have auto-save turned off, it wasn't doing it. This is of course because I always have autosave turned on. I suspect we'll find many other problems like this in the weeks to come.
Anyway, I'm typing this with autosave off, and the console window open, and nothing is happening, as you would hope. Now I'm going to choose Save from the File menu and see what happens.
Everything is rendered and the feed is built. I'd say the problem is licked.
Note to testers: See why it's important to say what you did? Somewhere in that narrative would have been "I chose Save from the File menu" and that would have pointed me right at the problem, because it isn't something I ever do.
