Hello.

I was tweeking paypal_standard.php, trying to change the subject line a little.
During my trial and error of doing this, I started getting "PayPal IPN Invalid Process" emails being sent to my debug email.
I've fixed the error I had in the file and it works fine, but I am still getting the debug emails from the first few problem attempts.
I have removed all the orders in the db thru the admin screen - still getting the emails.
I figure there must be a daemon somewhere that needs to be bumped, but I cant find anything.

I am using osc v2.2 rc2a, using the paypal sandbox, and am on a godaddy server.
Looking at the long headers of the email, it is coming from the godaddy server, so I figure its on my side, not the paypal side.

Does anyone have any insight for me?
Thank you.

For those who run into this, or something similar...

I traced this back to needing the proxy stuff set for using godaddy.
The following 3 lines were added to ext/modules/payment/paypal/standard_ipn.php and the endless emails seems to have stopped.

curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt($ch, CURLOPT_PROXY, "http://proxy.shr.secureserver.net:3128");

I hope this helps.

Yes if Your server uses a Proxy(godaddy does and some more server too have started using for security) then for CURL to know YOu need to add the above stated line.

This curl_setopt($ch, CURLOPT_PROXY, "http://proxy.shr.secureserver.net:3128"); will be different for different server.

Was having this problem consistently using the PayPal sandbox ... until I fixed a problem with the "tax" variable.
The variable used to override the per item tax was "tax" but as of late March 2008 is now "tax_cart". I made the change and presto, these recurring error emails disappeared.

Can you be more specific on what you changed? My paypal setup was working wonderfully until about a month ago, then I started getting these "IPN Invalid Process" emails...but the payments still seem to go through successfully. Trying to pinpoint the problem and solution, I do not use GoDaddy and I am unsure if my host uses a proxy so maybe your information applies to me.

Sure ...

In file catalog/includes/modules/payment/paypal_standard.php
In function "process_button"
In the $parameters array, changed 'tax' to 'tax_cart'

Hope this helps.
