osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now
Error when upgrading - Fatal error: Only variables can be passed by reference
I'm trying to upgrade osTicket for the latest version, and I'm getting the following error:
Fatal error: Only variables can be passed by reference in /var/www/html/include/class.plugin.php on line 555
I'm running CentOS 6.8 with Apache 2.2 and PHP 5.3.3
What is the problem ? Is PHP version ?
