Hi and thanks for your help,
We have had very recent trouble with IPN.
Debug IPN log shows success on all prior sale (4/2 was last prior), but today a paypal sale went through and no notifications were sent or customer added.
I have read and followed instructions in previous posts so can paste this entry from a debug log IPN test:
[04/19/2013 9:12 PM] – SUCCESS :Paypal Class Initiated by 173.0.81.1 eStore Version: 6.9.6.2
[04/19/2013 9:12 PM] – SUCCESS :Post string : [admin deleted post data]
[04/19/2013 9:12 PM] – SUCCESS :Connection to http://www.paypal.com successfuly completed.
[04/19/2013 9:12 PM] – FAILURE :IPN validation failed.
[04/19/2013 9:12 PM] – SUCCESS :Paypal class finished.
The paypal account IPN is enabled
The only thing different is I was told recently that a “needed new security firewall was added on the site” because “WordPress sites were under a viral bot attack”.
Can you point me in the correct direction to test/fix this problem?

I have set up a two step process. Fill in a form and submit; then add items to cart and pay.
The form came through this morning and for the first time ever, the payment notice didn’t.
When I looked at the Paypal account, it was clear the payment was made, but the IPN didn’t come through.
I went through the support forum looking for clues. I went to Paypal, found the transaction in IPN history, and had that payment notice recent… nothing came through.
Not sure why I should be using a sandbox at this point, but will be happily educated.
Thanks!

If it’s a plugin, see the firewall section in this link regarding a possible tweak you can do:
If your hosting provider is administering the firewall solution, the best thing to do is to talk to them and ask them to check if they are blocking PayPal IPN messages and if so to allow these messages through.
