[Plugin: Post Ratings] Can't see rating form

Hi

I would like to use this plugin. But I don’t see the rating form on my pages. I have enabled the plugin for pages. And I put the [rate] shortcode on the desired page.

Still, the pages look no different than they did before installing the plugin. I don’t see the form users are supposed to click on to give a rating.

Any tips?

Thanks
