Thread:Project:Support desk/Database error after updating to 1.21.1/reply (3)

Well, if you did a grep and found nothing, that's very strange, indeed. I've also done a grep and nothing found except for patches.

I have 1.21 and it has no problems for saving edits. Maybe you can try Manual:How to debug to get a stack trace of the error, identifying what file and exact line was trying to execute that SQL sentence to see where that field comes from.

Or maybe you forgot to point your webserver to the 1.21 installation directory and it's still pointing to the old one, while you ran update.php from the command line?
