Invalid or no certificate authority found, using bundled information

Question

I\'m getting started with the facebook API. I downloaded the example code from facebook, configured with my appID and secret keys.

Answer 1

Disable the SSL security feature

Though I don't recognize that exact error message, SSL problems when communicating with Facebook via the PHP SDK (and thus Curl) are common. Have you tried doing something like this?

Facebook::$CURL_OPTS[CURLOPT_SSL_VERIFYPEER] = false;

This will disable the SSL "Verify Peer" security feature so that it stops generating the error message.
