I am using the Paypal Framework plugin (http://wordpress.org/extend/plugins/paypal-framework/) and am receiving the following error when it tries to verify the IPN request sent by Paypal:
SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
I have tried setting the following wherever I believe it is about to make a curl request:
curl_setopt( $handle, CURLOPT_SSL_VERIFYHOST, false ); curl_setopt( $handle, CURLOPT_SSL_VERIFYPEER, false );
(just for testing purposes, I wouldn't do this in production). But the exact same error still occurs.
I've been googling this for a few hours now, and none of the methods suggested appear to be working to even find where it is that the problem is occurring. Unfortunately, the plugin author does not appear to be active anymore (the last forum posts are 2010, with no replies) and he hasn't updated this since 2010.
I am currently testing it with Paypal Sandbox, and when I visit the page that it is attempting to verify, Firefox informs me that its a proper certificate. Aside from this, everything else with the IPN appears to be working properly. If its of any value to anyone, I am currently hosted by GoDaddy.
Any input or help would be much appreciated.
Thank you in advance!
