بعد از نصب تم با خطای زیر مواجه شدم:

The parameters dictionary contains a null entry for parameter 'currentCategoryId' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult ManufactureNavigation(Int32m Int32)' kn 'Nop.Web.Controllers.CatalogController'. An optional parameter must be refrence type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
@Html.Action('ManufactureNavigation", "Catalog", new {currentManufactureId = currentManufactureId})
