Once you've gotten your new Minecraft server, unless you get a permissions plugin, you'll need to be opped to run commands.
OP or operator permissions is something that allows you to run administrative commands on your server.
Please note: Do not OP people you do not know or trust. Never believe people who say they are from places such as Planet Minecraft.
To op a player:
- Log into the CurseHosting panel at https://panel.cursehosting.com.
- Click on the server that you want to OP the player on.
- Enter `/op <playername>` where <playername> is your Minecraft username then press the enter button.
And there you go, you're now OP.
We recommend later getting a permissions plugin such as LuckPerms later as permissions can be properly configured to allow things such as ranks.
