Can´t ´do any command anymore as admin?

sry - solved!

hi, i can´t do any command anymore. I am admin. I have deaktivated permission-system(Luckperms on the backend-server where i am). Now i am getting no info after dooing a command. I opped me, and an can use commands as feed from the console. But not ingame. What can this be?

omg - i am happy
i used in permissions-file:
permissionx
instead of:
- permissionx
