I am learning how to use K2 component. I have noticed that after AceSEF component enabling voting in K2 items stopped working. When you click on one of the stars spinner icon is showing and page hangs.

Installation details:
Joomla 1.7.2
K2 2.5.1
AceSEF 1.7.1


Example of K2 item where voting doesn't work - labaj.com.pl/j17/hello/item/140-i-jeszcze-jeden-test
