[Plugin: Infinite-Scroll] Infinite Scroll Problem Bigfoot Theme

Hi! Could you help me to make this plugin work on my website?
Selectors now are like on this screenshot – http://rekordyguinessa.pl/wp-content/uploads/2012/03/settings.png
and my website is http://rekordyguinessa.pl/

What’s wrong?

Infinite Scroll State is ON
Debug Mode is ON
Scrolling Behavior is Automatic

Thank you
