WP-PostRatings cannot rate on WordPress 2.8

Yes. I discovered the first issue after upgraded to WordPress 2.8. The WP-PostRatings developed by Lester ‘GaMerZ’ Chan cannot work. It failed to rate. What is going on here? After searching around, I discovered that the new WP-PostRatings 1.50 will generate some JavaScript codes at the footer. It requires <?php wp_footer(); ?> code in your theme footer template.

My current theme does not have <?php wp_footer(); ?> code at footer. So WP-PostRatings fail to rate. So if you are facing the same problem as I do, just double check that your footer template has <?php wp_footer(); ?> and header template has <?php wp_head(); ?>.
