    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?

    It looks like you are doing sandbox testing but you didn’t enable the “Enable Sandbox” checkbox in the eStore settings? So eStore is trying to validate the IPN with live PayPal site which is failing.

    Well, not really. The site’s been working fine for over a year.

    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!

    The firewall you refer to – is it a plugin or something on the host?

    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.
