The polling plugin can track who made a vote several different ways to try and stop people from cheating and voting multiple tiimes

If you go to the Polls Admin section, Tracking options you can set how votes are tracked and change it to suit your setup.

========================

In this section of the Polls setup, you can specify how users are tracked with respect to multiple votings.

If you don’t care if folks can vote multiple times in a poll, then disable this setting by setting it to none. You can track voters by cookie, IP address, a combination of cookie and IP or by user id.

Tracking is not an exact science. IP addresses can be spoofed and cookies can be removed or blocked. Also, if using cookies and/or IP, different users will not be able to vote from the same machine. If you are only letting registered members of your site vote (done via permission), then tracking by user id will be the best solution. If you are allowing guests to vote, we recommend the cookie and IP tracking method for the best chance of users not casting multiple votes

===================

Have you given users permission to vote in polls? Separate permission for creating polls too.

I’ve set to track by user so that’s resolved my problem. Thanks.

good news… thanks for the update…

I’ve got the same problem, but can’t see where to set permission.

I went to polls and tracking was already set to User ID.

Thank you – people seem to be able to vote now.

I don’t want to vote but want to see the results. I can go to the manage polls panel to look, but wondered if I should be able to click on “see poll results” which is in the actual post. When I click on that nothing happens. Do I have to have voted to see the results in the post?

Depends. There is an option for that. If set, it applies to everyone.
