Notification de Paypal refusée:invalid transaction

I have been receiving many emails stating 'Invalid Transaction' (Notification de paiement de Paypal refusée:invalid transaction‏) and a lot of my transactions don't receive IPN's from Paypal. Anyway to easily solve this issue and figure out a way to ensure this would be eliminated ?

Hi,

Some transactions are correctly made ?
Can you give us some screenshot of your paypal configuration ?

Hi Xavier. Effectively, some transactions are working ok and we receive the IPN, some others we don't and they remain at the 'Created' status. You can check my configuration, (I intentionnally removed the email address), in the attached document. Thanks for letting me know, I'm also checking on Paypal's to find out if they're would be additionnal Ip addresses to add to the list.

Hi,

Are you sure that the customer confirm the payment on PayPal for the transactions ? (the missing ones)
Thanks to enable the debug option in the PayPal payment method settings, then check if there is any errors returned in Configuration > Main > Files, error log file.

Hi. I'm sure the clients paid their orders because I see their payment in Paypal and status doesn't change. I tried the error reporting and I get an error (please see attached). Verified everything server-wise, all ports are open and Paypal IP addresses added in the 'allowed' ip in the firewall. So now I assume it's either Paypal not sending the IPN or the listener not working properly. On Paypal's side, I would be very surprised as I sent and resent IPN (from History) and it doesnt change anything. So we're back at the listener.

Waiting for your feedback.

Thanks.

Hi. Here's the debug info I get WHEN the IPN works (I don't have anything when it doesnt work)
