PHP Problem with the SSL CA cert (path? access rights?)

Had this happen to two servers which use the PayPal IPN, both at around the same time.

Fix was to restart Apache.

Just upgraded to PHP 5.5.17 and this is when the trouble started. The server runs PayPal transactions and cURL started failing on this error: "Problem with the SSL CA cert (path? access rights?)".

I tried regenerating the certs, modifying the curl options, nothing was getting me anywhere. The solution was to simply reboot the server (CentOS 6.5 in my case). Hope this helps someone.

If you are getting "Problem with the SSL CA cert (path? access rights?)" it may very well mean that you have either deleted everything from /etc/pki/tls/certs/ or have set invalid permissions (CHMOD).

If you are using RHEL/CentOS, try yum reinstall openssl ca-certificates -y
