Error on Shopping Cart when upgrading to 4.0

I select one product and then try to move to the Shopping Cart and I'm getting an internal error message.

When I check the administrative log, I have the following error:

One or more compilation failures occurred:
D:\home\site\wwwroot\Views\ShoppingCart\_CheckoutAttributes.cshtml(92,31): error CS1061: 'IHtmlHelper<IList<ShoppingCartModel.CheckoutAttributeModel>>' does not contain a definition for 'DatePickerDropDowns' and no extension method 'DatePickerDropDowns' accepting a first argument of type 'IHtmlHelper<IList<ShoppingCartModel.CheckoutAttributeModel>>' could be found (are you missing a using directive or an assembly reference?)

Any advice ?

Thanks a lot.

There is no _CheckoutAttributes at ShoppingCart in nopCommerce 4.00, look at GitHub source.
I suppose you have not uploaded proper views after upgrading.

I cleaned the whole folder, copy the new files and everything worked fine!
Thanks a lot!
