[FIXED] Error 500 when including/requiring src/facebook.php from Facebook PHP SDK

Issue

I'm working to implement a Facebook login for my website. I have limited knowledge of php debugging so I'm more or less looking for a good approach to debug this.

As soon as I include (or require) the facebook.php file, with no other SDK interaction, Apache will 500 my PHP script.

include('fb-php-sdk/src/facebook.php');

fb-php-sdk is a directory within the directory that contains our PHP script (also the document root)

Solution
