Re: Paypal IPN double orders
Because you gave your Zen Cart address as the Instant Payment Notification URL in your PayPal account profile settings. But, since you need the IPN feature enabled if you're going to use the IPN module, you've got to point it to "something".

Granted, you could always turn off the IPN module in your store, and use Express Checkout instead.
Well, since you stripped out all the actual transaction data, I can't verify anything about them.

But, looking at the 2nd two files you shared, and strictly looking at the transaction amounts, I don't see how you think they're duplicates. One is for 4.99 and says it was successful, and the other for 14.30 and was not successful because it didn't find an existing matching order waiting for IPN validation ... which suggests it didn't even come from Zen Cart in the first place.
If you've shared *all* the log data you have, then there's nothing obvious indicating the cause for duplicates. Maybe you have an addon that's clashing somewhere?
