Hi Tunde,

This appears to be an issue with the server’s configuration. Here is the important part of the IPN log:

Errors resulting from the execution of curl transfer: error setting certificate verify locations:
CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none
[03/31/2013 10:43 PM] – FAIL: IPN Validation Failed

This is very similar to the error discussed in this StackExchange thread:

It could be that there’s an older version of cURL installed on the server, which if that’s the case, it could be upgraded. You can contact your host’s support and let them know about the specific CApath error you are seeing and they should be able to help you with that.
