I have members in my membership site and it's forum. I stay close to them and give them incentives in exchange of buying something that will be useful for them + will make me money. When they do that, I'll give them VIP membership for free. So what I did was get a dozen of my members to buy something that I am promoting in Clickbank. I sent xxxx amount of traffic directly to my hoplink to make the sale look real. The problem arrives when they try to buy the product, all of them got this same message when they hit the "pay now" button -- > "Unable to process your order at this time (0)" All 11 of them got that message when they try to purchase the product. What went wrong?
