Those are the copies of the old emails. In your last post you asked for old emails and now you say that they aren't help. If those aren't what you asked for here:
I'll need to see the subject and first few lines of the email that eShop sends you for one of these failed payments to be able to look into this.
What did you need? I would like to give you what you need to help solve the problem and I'm doing the best at what I think you are referring to.
Let me try explaining everything over more clearly and in one email because it may have gotten jumbled throughout the multiple messages.
The person makes a payment.
Paypal always seems to accept the payment. Normally because they accept the Payment I ignore the issue.
Paypal are now sending me the warnings that the IPN is invalid. They are sending me these messages repeatedly for the same sale. Prior to this I only got 1 notice.
Within eshop there is a lot of payments under the deleted tab in "orders" that I did not delete. These items were paid for. Their status still "processing."
There are a few items under the "Failed" orders tab. Those were paid for as well, but they have transaction ids. These also however had the failed IPN.
This information here is not about a problem, but information that should hopefully help solve the problem.
For a while I had two email addresses listed in eshop and paypal. For a while adding the second email address seemed to solve the problem.
Oddly all the information about my sales were sent to the secondary email not the primary. This was irritating but at least I was getting some messages. And the IPNs had stopped for a while, but now they are back. The problem of the IPNs have been intermittent since I got eShop which has been for quite a few months if not over a year throughout the updates of WP and Eshop.
I have now tried to only have one email in paypal and eshop as I read someone else had the problem and that fixed it for them. I have continued to receive the emails from Paypal threatening to block my website from accepting Payments due to bad IPN requests.
I hope that this is clearer and provides all the information you need. I don't know what other emails you wanted when you asked as I have provided ones from both eshop and paypal to try to help clarify the issue and do not have any other related emails to my knowledge.
