[Plugin : WP-Polls] Nothing happening when I click submit

I’ve installed the WP-Polls plugin and have setup my first poll OK. However, on the page it does not allow me to submit the data upon clicking the vote button and just does nothing?

Also, I just get this animated GIF saying ‘Loading’ and the View Results hypertext link doesn’t do anything either

What’s the crack? Here’s my page:
