CurlException: 77: Prblem with the SSL CA cert on facebook login

Question

I'm trying to launch login system with facebook using facebook PHP SDK, but I get this error:

CurlException: 77: Problem with the SSL CA cert (path? access rights?)

I have tried it on another server and it worked brilliantly. On this server where it does not work I have tried everything I could find on the Internet. I have tried these solutions:

• http://ahoj.io/facebook-php-api-without-curl-extension
• adding fb_ca_chain_bundle.crt (yes, I chmoded 777 the file and the directory)
• adding cacert.pem
• adding curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); before curl_exec()

None of these worked. Is it possible that hosting providers could solve this issue? Because a few days ago this script worked brilliantly on both test servers.

Answer 1

I had the same problem. Recently, Facebook changed its encryption, so I installed Mcrypt extension and it works again.
