So if the servers are ruled out and the same Paypal account works on one site but not on another then the only thing that is left that I can think of is the content of the IPN, which is not recognised in all cases by Actinic.
Does the order number form part of the IPN?
Do the failing sites have modified order numbers?
Is there a checksum on the IPN?
Does anyone know what the actual content of the IPN is?
