I am trying to make a configurable product (clothes with size and color) shipped. When I create a simple product I see shipment method :

But when I select a configurable product (choose the size and the color), I don't see the shipment method and I'm forwarded directly to the payment page. And I must say these products have weight.

When I see to the DB (table catalog\_product\_entity), I see the main product is Configurable while the others (combination size-color) are virtual. I hanged the "virtual" attribute to "simple" , still didn't work
