Hi
We are experienceing similar problems, we have just opened the account and for the past 5 days have had a 7% failure rate on writing to the database, most get through, some customers send duplicate payments for a single order, and others send payments with no order which we have to find.
We are on 1and1, speaking to Protx we found them no use at all they are sayi9ng it's osCommerce fault they are sending the info back??? It got so bad that on Tuesday we removed the system complelty as we didn't really understand where the missing transactions were going, we can now trace them but customers are not happy getting error pages so we will have to find a fix very soon or lose Protx.
The only advise they give is "You're stuck in a 3 month contract so you will have to pay fees until then", thanks...
Which date/contribution fixed it for you Geordiedan? The one I can see say that the order IS stored, yet the customers get the error message.
