I Got 500 Internal Server Error from Cyberpanel IP:8090.
Website and WebAdmin :7080 is working fine.
I tried systemctl restart lscpd - and its running just fine.
Sometimes having the same problem.
I used the v2.1.2 Stable. there was no problem. but for some reason i upgrade to the latest 2.3.2 stable.since then this problem started. then i downgrade to 2.1.2 stable. but the problem is not solved.
Maybe some packages of mariadb is missing/deleted by the OS while doing some upgrade or update actions
If the problem is still unresolved, I will suggest you to reinstall mariadb (be careful while doing this as its sensitive…if anything wrong happens, your mariadb will be down and thus all your sites). Better you take snapshot of your whole server before trying this for safety.
