All,

I am installing on a newly minted CentOS7 install. I have SELinux set to permissive mode. When I attempt to run the installer I get an HTTP 500 error. My httpd log file shows the following error.

[Sun Mar 31 22:05:50.498423 2019] [:error] [pid 29618] [client 192.168.1.31:52940] PHP Fatal error: Call to a member function getAllowIframes() on null in /var/www/html/osTicket/setup/inc/header.inc.php on line 2

I am running php 5.6, and Apache 2.4.6.
