It turned out to be a transitory bug, it all seems to be working now.

What happened was when I saved a draft of a post the text was not saved, the title and tags were saved. I deleted the empty posts, because I didn't want them, and I had made a few. I probably shouldn't have done in terms of bug tracking. They all had the title programmatic prediction market, if that helps you track down the sql requests.

I also noticed that there was no most controversial posts or top posts, when I clicked on them.

I'm wondering whether it was some interaction with noscript a javascript blocker I have, but I haven't changed the settings recently.
