Invoice with no attributes or no invoice

[Bianca]

Hello,

So I've spent two days trying to find an answer for my problem: when I started my shop the orders went just fine but since Monday something happened and I don't get any new orders only new customers and I have to check on their details to see if they placed an order and change the status to Payment accepted and only then it will appear in the Orders. That I don't mind to do but after I change the status and I look at the order I get the sum of the order but no products and no invoice and if I check the customer's cart I cannot see the sizes for the products. Please if anyone can help me or if you saw somewhere the same problem and I didn't find it. And I'm using 1.2.5
