Ok, so your PHP version is NOT the problem. Have you tried turning on debugging? Below is from the wiki:http://osticket.com/wiki/Installation#Self-Help_TroubleshootingSelf-Help TroubleshootingIf you can not find any solutions to the problem you are having, you can enable the "Show Errors" flags located in /bootstrap.php (or /main.inc.php in older versions):
#Don't display errors
ini_set('display_errors',0);
ini_set('display_startup_errors',0);Change this to:
ini_set('display_errors',1);
ini_set('display_startup_errors',1);Then errors should be displayed either in your web browser or in your server's error.log file.
