Typically PHP errors are logged by default in the Apache/Webserver log. This is on Debian, don't know if Redhat behaves the same way.Did you do any configuration changes on your Apache server i.e. httpd.conf?Whats your httpd.conf look like?Did you create a virtual host for your website/ticket-site?Was it functioning before and then all of a sudden you started getting that fatal error? If so, was there something you did before that could have prompted that error?If you're running on cPanel, it stores logs in a different location, typically right here:/usr/local/apache/logs/error_logIf you can't figure it out run this command and post the output here:php --info | grep error
