I migrated our OSticket installation from Debian 10 to Debian 12 by exporting the database from old server to new server and copying all files from old server /var/www/html/osticket to new server /var/www/osticket. Gave the proper permissions.
I am able to login to the new server as admin; however, if I try to click on closed tickets, it just sits there for a minute and then the page refreshes; however, it does not take me to closed tickets. Also, if I click on 'Admin' panel and then I tried to click on 'Agent Panel' , the screen freezes and then it stays where I am.
Please see attached server config.
I had a similar issue back in 2021 when I attempted to migrate from CentOS 8 to Debian 11. I ended up migrating to Debian 10 which worked without issues.
Thanks for your help!
