This question already has an answer here:
- Cancelling an Upvote (Downvote) 1 answer
I saw an answer to a question and thought there was an error in it. I wrote a comment and downvoted it. Then the original poster responded to my comment and it turns out I was mistaken and the answer is correct as originally written. Now I can't undo my downvote because the answer was not edited. The answer was fine all along, I was wrong in downvoting it. Why can I not fix this?
