25th March 2015 – SSL/Certificate Errors

only affects versions prior to 2.1.7.7

I am aware that since yesterday there might be an issue with the paypal plugin rejecting the included certificate and – although payments will be accepted – the order is not being passed on to you/the restaurant.

this sort of redundancy was never intended to be part of the plugin (i.e it was never the intention to force people to renew their license because of this behaviour)

how to fix:

if you DO have an active license:
just update the plugin/gateway (it will from now on use certificates included with wordpress so this issue should never arise anymore)

if you DO NOT have an active license:
open wp-content/plugins/wppizza-gateway-paypal/ipn/ipnlistener.php
and REPLACE the line that reads (at approx line 98)

curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__)."/api_cert_chain.crt");

with the following

curl_setopt($ch, CURLOPT_CAINFO, ABSPATH . WPINC . '/certificates/ca-bundle.crt' );

and save
