How To Change Player’s OP Level?
Head over to the Game Panel and make sure the server is not running.
Go to the “Files” tab and open the “ops.json” file. Before the player’s name appears in this file, make sure you’ve given them OP permissions (/op <playername>).

Find the player whose level you would like to change and change it.

Save the file and start your server.
Congratulations, you've successfully changed the player’s OP level. If you have any issues or concerns, please contact us through the ticket system.
