I have a client whos' site is OS Commerce.
They use PayPal as their processor. The payment system isn't working and unfortunately it's not giving me any kind of error message to pass on.
PayPal took a look and said they should try a different module. I am not an osCommerce developer.
I'm entering in the lowest value but in truth, I have no idea how long this will take so if you need to bid above the value, go right ahead.
That's about all I know
