Hello, I am experiencing this same problem using a MAMP environment in OSX - I looked to see if this was a patch I could make to my api files but it looks like maybe I've got a newer version as this line isn't even in apiCurlIO.php .
Fatal error: Uncaught exception 'apiIOException' with message 'HTTP Error: (0) SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed' in /Users/jrgweb/Sites/oauthTest/
This error means curl was unable to find a certificate bundle on your system for validating SSL connections. Since this is a frequent issue for PHP deployments, the latest version of the PHP client (on trunk) contains its own bundle for validating SSL connections when making API requests.
Simply grab the latest version of the client on trunk and things should just work:
