I've added a poll and when I'm not logged-in the module says "You have voted on this poll. Thank you for your feedback." But the Total Votes count is 0.
I can not find out what is going on. I can not find a option to make the poll available for guests if that would be the problem.

Also it says: "Note: Results are hidden from public viewing. Please contact poll manager/us to know more about it."
Where can I find this option?
