Magento Ajax Popup by Hussey Codings is not working in home page. But working in other pages fine.

We have upgraded magento site from version 1.7 to 1.9. Magento Ajax Popup by Hussey Codings is not working in home page. But working in other pages fine.

Inner pages like category listing page and product view page it is working fine. But the add to cart is not working in homepage only.

The code for the add to cart button is coming like the following:

<button class="button btn-cart" onclick="setLocation('http://www.akku-laden24.de/Magento_New_Upgrade/checkout/cart/add/uenc/aHR0cDovL3d3dy5ha2t1LWxhZGVuMj..." title="In den Warenkorb" type="button">

Site URL: http://tinyurl.com/neeevac

And it redirects to empty cart page. 

Any solution for this problem?

Please check first if these points are ok:

1. The extension which you are you using is compatible with magento 1.9
2. The product listing displayed on the home page is using the default listing functionality.
