Server responded with status 500

Hey,

i got a problem with my Ajax Filters. 

If i try to filter any results the server reponses always with a status 500 (Failed to load resource: the server responded with a status of 500 (Internal Server Error)), this happens on the "getFilteredProducts" method.

I can't debugg the site very well because it is aleready live on a test server, but the nopcommerce log gives the following infomation:

"The given key was not present in the dictionary


System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at
ASP._Page_Themes_TC_Views_Shared__StockInfo_cshtml.Execute() ... "


Do you have any ideas whats the problem? I already tried to uninstall and install again, also replaced the plugin with a other version. 


Best regards,
Govinda 

Hi Govinda,

The fastest way to see what is wrong and advice is if you submit a ticket providing your nopCommerce version and url to your store.
