Hello guys... again..

So I did a order step by step without any issues in my testing server... When I try to implement it in the production server, the macro that creates and adds the product to the basket crashes with no aparent reason.

Here's the code:

    var request = HttpContext.Current.Request;
   
    var obj_products = from items in Product.All().Where(x => x.ProductDefinition.Name == "productdefinitionName").OrderBy(z => z.Sku)
                       select items;
    Product[] arr_product = obj_products.ToArray();

    var obj_properties = from x in ProductDefinitionField.All().Where(y => y.ProductDefinition.Name == "Subscription")
                         select x;

    ProductDefinitionField[] arr_productProperty = obj_properties.ToArray();

    int num_productArrayLength = arr_product.Length;
    int num_productPropertyArrayLength = arr_productProperty.Length;
    int num_rowCount = 1;
    string str_productName = "";
    string str_prodDefinition = "";
    string str_MonthlyFeeValue = "";
    string str_productId = "";
    string product_Sku = "";
    string str_query = "";
    bool bool_HaveProperty;
    bool bool_hasBasket = true;



    if (request.QueryString["cartcmd"] != null && request.QueryString["cartcmd"].ToString() == "Add")
    {
        str_query = request.QueryString.ToString();
        var parsed = HttpUtility.ParseQueryString(str_query);

         product_Sku = parsed["productID"].ToString();
       
        else
        {
        if (SiteContext.Current.OrderContext.HasBasket)
        {
            bool_hasBasket = false;
        }
        else
        {
            bool_hasBasket = true;
        }
        PurchaseOrder obj_basket = TransactionLibrary.GetBasket(bool_hasBasket).PurchaseOrder;

        obj_basket.OrderLines.Clear();
        obj_basket.Save();

       
        TransactionLibrary.AddToBasket(1, product_Sku, null, true, true);

     
            if (!obj_basket.OrderLines.Any())
            {
                <p>Cart is empty!</p>
            }

 
   
        //Redirects to the billing details page
        }
       
    }

I only have 2 products without any variants, and they are identical to each other in both servers... pricing (>0,00DKK ), sku, definitions... everything...Same with the product and catalog definitions, and both stores are identical (except the host name...)

When I press one of them, it redirects to the same page, and sends the product sku through query string, then I get the product sku via the query string, create the basket (if there isn't one created), and add that product to the basket and redirect to the billing details page...

I have tried the other overload for the addtobasket method, and it still didn't work.

I can't find the reason for it to work in the dev server but not in the production server...
