I have another thread regarding PayPal IPN (I have no preference to which PayPal module I use, but neither of them are working for me)
I apologize for the cross post on the other thread.
I would love help with figuring out the PayPal Express issue and will keep my comments to this thread.
The error message does not occur until you have completed the transaction.
If you would like to view the error message I have created this product (that only costs a penny) and you can choose Walk In from the shipping selection so that no shipping is charged)
