"Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request." Is generally an apache error (Or more specifically, its an error about an apache error. The 500 part is the real error, but both are generated by apache), not a php error. Looking in your apache error log (Sometimes located in places like /var/log/apache/error_log ) is more likely to have fruit than your php error log.
