Can I vote

I tried voting in the Poll box on the home page here. I got a message something like, “you can’t vote because you’ve already voted today.” I haven’t voted in at least a month. Thought you might be interested.

I thought someone changed the vote once-a-day rule to vote once-only to avoid ballot stuffing but never changed the denial message.

Well I don’t remember voting on this issue, but it could well be early dementia, :-O.
