Hello! I wanted to create a command where i can whitelist a custom player (because for the /whitelist command you need op). The command is /cl (player). But when I run my code it says in chat: An Internal error occurred while trying to perform this command. I have no Idea what the problem is. Here is the code: String name = args Player target = Bukkit.getofflineplayer(name) Player.addwhitelist(true) Idk if it helps, but the .getofflineplayer is crossed out. Does any1 have a Idea whats the problem? Thanks in advance!
