404 Not found error message

Hello, I’m having this error 404 Not Found message since I migrated omeka 3.1.2 on my new server. I even changed the value of debug.exceptions to true, on the application/config/config.ini, but it changed nothing. Could you help me to solve this issue please?
Here are the following informations about the new server :

  • Debian 12
  • PHP 8.2
  • MariaDB 10.11.14
  • Apache version 2.4.66

Is it a “plain” 404 page like the one shown here? If so then the problem/solution is likely one of the things listed there.
