The "Polls" app in the Site Map allows you to manage lots of polls - in itself it is not a poll. It looks like while you had a poll in this app but you have managed to delete it (sadly polls can not be undeleted).

I have created a test poll in the Polls app - if you add a Polls includelet to a page you should now see that my test poll appears as an option. You probably want to delete my test poll and add your own though!

Note that each poll can be enabled/disabled independently within the Polls app. You might have lots of different polls defined but only one or two of them enabled. I think maybe you confused enabling/disabling the whole Polls app with enabling/disabling an individual poll within that app.

Hope this helps!

Thanks
