fix 2 onlineshops and 1 website

We have 2 Web shops and one Website with small Problems. The links to the 3 Sites and the error description you can find here: [login to view URL] On this site all the links do not work [login to view URL] The order cannot be processed. You can put goods in the cart and you can open the cart. But you cannot finish the order. After pressing the order button you get an error. [login to view URL] The order cannot be processed. You can put goods in the cart and you can open the cart. But you cannot finish the order. After pressing the order button you get an error. Furthermore the shop doesn’t show the articles in the categories. If you open an article directly, you can see the article details. But if you open an article category the shop don’t show the articles which are in this category. The problem is since we moved the sites from one hosting provider to another. After everything is working we will move the original domains too and you have to update the 3 sites that they will work with the original domains. Both shops are running on x-cart ecommerce engine. The second thing to do is to change the impress and contact details on all 3 sites.
