I used softaculous to install osticket in a plesk environment (ubuntu linux)
PHP 8.1.26
osticket 1.18.1
I did a clean install on a freshly set up server
and I get a blank screen when I visit the URL in my browser.
I checked the server logs and see this error
AH01071: Got error 'PHP message: PHP Fatal error: Cannot declare class Event, because the name is already in use in /var/www/vhosts/olt.net/httpdocs/helpdesk/include/class.thread.php on line 0'
