[abraham]

Can you replicate the error without the framework? What version of TwitterOAuth are you using?

[fsteinbauer]

I doug deeper, and discovered that curl returned errorno: 77
error: Problem with the SSL CA cert (path? access rights?)

After changing TwitterOAuth.php:277 from CURLOPT_SSL_VERIFYPEER => true, to false it worked for us.

Why do you need option VERIFYPEER enabled?

[abraham]

Without CURLOPT_SSL_VERIFYPEER there is no verification that connections are with Twitter. You should instead figure out what the problem is with reading cacert.pem.

[fsteinbauer]

I created Pull Request #315, so an exception is thrown, if there is no valid /usr/local/share/ca-certificates/cacert.pem
