I've been using this plugin for months now, and everything has been smooth as silk. But now I seem to have broken it

I updated to the latest Calibre (.8.27) tonight, when I first noticed that the link for "sync now" was greyed out. I thought it might be a problem with the new Calibre, so I downgraded to .26, but my Kindle still won't sync. Calibre sees that I've plugged it in, but the Reading List doesn't run automatically (and since it's greyed out, I can't run it manually)

I rebooted my laptop (I'm on a Mac, OS 10.7), and still no joy. I had previously reformatted my Kindle 3, but I thought that everything had been running smoothly again. Obviously, I missed something.

Help, please. What do I do next? Am I reduced to using "send to device" like a caveman?

Thanks.

ETA
I ran calibre-debug and my output file is below. I see that the reading list plugin says that no sync is required (that's not true, there are 2 books on my "sync" list). That explains the lack of an automatic sync, but it doesn't explain why forcing a sync isn't possible.

Spoiler:
