I seem to experience the error message: "Error business. Order ID XX" and cannot seem to find a way to fix it. I tried changing various options according to what I could understand from the people who experienced similar issues in this forum but no luck. I'm using the sandbox option and always get this error when asking for paypal return information. Without return option, I don't see the order in the order tab...Does anyone know why this is happening ? What is the solution to this error?
