Add to cart button not working

The add to cart button is not working anymore. Both in module and on product page, the add to cart button doesn't work anymore. I've updated to Business and I've upgraded to PHP 5.4.

-- url of the page with the problem -- : wolkietalkie.com
-- HikaShop version -- : 2.3.0
-- Joomla version -- : 2.5.18
-- PHP version -- : 5.4
-- Browser(s) name and version -- : Chrome and Safari

Hi, it was an error on ModulesAnywhere, after updating this extension, the problem was solved!
