Duplicate Zen orders from Paypal IPN

[ronlee67]

I use Paypal Website Payments Standard (not Pro) and recently been getting random duplicate orders in ZenCart with the same Paypal transaction ID.

I'm not sure if this is related, but I also noticed that Paypal is not processing AMEX charges giving customers a message to the effect that they are unable to process using that card and to try another card. (Sorry, I don't have the exact error message and don't have an AMEX card to test with)

In the case of the duplicate orders, I don't know if the customer may have tried to use AMEX first and then another card but there is only one Paypal transaction ID number and it appears on both orders.

You'll see from other similar discussions that some people who've had similar symptoms have met with some degree of success by blanking out the PDT Token value in their ZC admin.

Thanks Dr. Byte. That was done some time ago. I see elsewhere in the forums now that Paypal is having problems with the IPN and numerous Zencarters are involved. I disabled Paypal IPN on my sites until they get it sorted out.
