We only have 1 sales discount on this solution.

The discount is not set to deactive when you open the discount. The font color is gray when opening the discount page but after opening the discount and right away push save and close the font color is black and the discount works fine again.

The sales discount is a custom made discount. The discount code follows the standard DW code where i use the overridden method ProcessOrder in SalesDiscountProvider.

Here is my Sales Discount code:

using System;
using Dynamicweb.Extensibility;
using Dynamicweb.eCommerce.Orders;
using Dynamicweb.eCommerce.Orders.SalesDiscounts;
using Dynamicweb.Extensibility.Editors;
using Dynamicweb.eCommerce.Prices;
using Dynamicweb;
using System.Collections;
using System.Data;
