I am using XAMPP for development. Recently I upgraded my installation of xampp from an old version to 1.7.3. Now when I curl HTTPS enabled sites I get the following exception Fatal error: Uncaught exception ‘RequestCore_Exception’ with message ‘cURL resource: Resource id #55; cURL error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
