Thanks for your reply. I did follow the instructions and I reinstalled the plugin after upgrading.
Then they should be working fine. When did you download the Alfresco theme package?
The Ajax Filters work only on category/manufacturer pages but you have said that " Ajax Filters on the products page". Is this a typo or you really meant the product page?
I downloaded the Alfresco package just yesterday, so that should be fine right. I meant category pages, yes. Sorry for being unclear.
