Hello! i've got a problem that i didn't notice before, the problem is if i make an order being loged-in wp, it doesn't give me any fault. But if i appear as a customer or user,who is not loged-in(you can test it). The confirmation message doesn't appear when i finish buying, as the one i've sent attached as image;in its place appears this message(), but in the end, the order is perfectly realized.
The problem is that if it appears in the link's screen, the customers will think they haven't done it correctly and they do it again and again.
