WordPress › Support » [Plugin: Donate Plus] FATAL ERROR No Reply at all Posted IPN variables in order received:

I'm trying to set up donate plus on my site, and am getting this error in my e-mail box when I receive a donation:

Subject: Donate Plus - Paypal IPN Transaction

"FATAL ERROR No Reply at all Posted IPN variables in order received:"

Then it proceeds to list all the variables for the IPN. It seems like the plugin is not properly interfacing with Paypal's IPN. I have in enabled in my business paypal account, but am unsure what's going on.

Because of this error, no credit is given on the donor wall for donations... :(

Does anyone have any ideas? Thanks in advance for your help!

Ditto with problems.

I was able to test to the Belahost.com site and veryfy IPN success with the PP sandbox, but I can't get the real PP to give back a valid IPN.

They must have changed something at PP.

Help!

I have found out that this problem is because PP has now put up a 301 redirect to https://www.paypal.com/cgi-bin/webscr from the http version.

Since the script only posts via unencrypted http, it fails because it can't submit to the redirect, and has no smarts to submit via SSL.

I'm working on modifications to the paypal.php script that will use libcurl (linux/unix) to post the IPN reply via SSL.

Sorry about the testing, but I need the code to come through OK.

Anyway, the problem is solved. You will need to have compiled in curl support when you built PHP. I'm not sure if this will work on Windows or not.

This solution assumes the following: That you are on a Linux or Unix system, and have access to the GNU version of the patch program.

First, copy the following into a file called paypal.php.diff in your home directory on the server:

*** stock/paypal.php	2009-10-23 20:17:17.000000000 -0700

Now, assuming you are on Linux/Unix, and have the GNU version of the patch program (necessary), then cd to (WP install dir)/wp-content/plugins/donate-plus, and run the following commands:

cp -p paypal.php paypal.php.bak
cp -p donate-plus.php donate-plus.php.bak
patch -p1 -i ~/paypal.php.diff paypal.php
patch -p1 -i ~/donate-plus.php.diff donate-plus.php

That's it. You will probably want to verify that the live/testing settings in paypal.php are still what you want, and that the host to POST to in donate-plus.php is set properly as well.
