K2Store + Cache not working properly

I have a site that is using the GK NEWS template (http://www.nationaljuniorhockey.com) and I am using K2 Store as an ecommerce solution. Everything works great when the Cache plugins are activated (yes, I enabled both GKCache and System Cache - in the order recommended) except for the Store and Cart.

My Cache settings are as follows:

a) Enabled Plugin - System GKCache
b) Enabled Plugin - System Cache
c) Global Configuration -> System -> Cache (on-conservative) | Handler = File | Cache Time = 5

With caching enabled, the cart doesn't update correctly when adding new/additional items or updating cart quantities. For instance:

1) Go to store, pick an item and click view cart.
2) Decide I dont want item and click "remove item". The Cart page currently being viewed appears to update and the cart module in the "inset" position appear to update. However when I navigate away, pick a different item and then go back to the cart.........the previous item that was removed is still there and the new item(s) I selected are not.

If I disable the system - cache (basically turning off caching) - everything works as intended.

Is there a way to enable caching on my site and still have the cart work properly or am I stuck ??? I have even gone so far as to install a plugin called CacheControl and set that up to disable caching on all URL's with the rules: option=com_k2store think that this would help - but no luck on that either.

HELP !

Hello,

Please try to disable the GK Cache extensions - in fact these plugins are dedicated to the non-responsive templates. And please use only standard joomla cache system.

I've tried every combination of cache extensions being enabled or not. Nothing seems to help except when i disable the default system cache plugin. I'll keep researching and see if I can't find a solution.

Please check if it is possible to disable the cache for the cart - or consult it with K2Store support.
