“Vote too old to be changed”… but I haven’t voted!
I can't vote on this question I get the "Vote to old to be changed" message even though I never voted on it. Clicking on the score shows no up- or down-votes at all.
Edit: I think I understand what happened. I first saw the question and upvoted it, I then realised the owner of the question was not a member of SU (migrated from SO) and removed my vote. (I usually don't bother with questions with no owner). Later I came back and found that the user had registered and wanted to place my vote and encounter the error message.
