Please see this problem description at Meta.StackOverflow
We never create a field called author, so it being there isn't our fault. It's possible that another userscript creates a conflict though. Can you provide a complete list of Stack Exchange related userscripts you have installed so that I can check for conflicts?
Ah, nevermind. The author field is actually in the page natively, that makes a bit more sense.
I was just about to suggest it.
For the record, for me, the list is:
Another user who repro'd the problem reported to me he had:
"the editor kit, @nhinkle's side-by-side (which breaks on beta), duplicate Qs and auto comment userscripts"
Turns out this was thankfully not our fault. :)
Thank you for your prompt attention, and sorry to waste your time.
Oh, no problem, I'm just glad it's resolved either way!
