    First of all, it's a nullpointerexception, second of all would you be so kind to give us the exception itself so we can see what the issue is?

    Could you give us your listener?

    Don't have a listener for that

    Did that, no change

    Ok, i know the problem now, the config is not getting any information... it doesn't add the survival-rules etc ... why not?

    You're only checking for an argslength in your oncommand, not for a command....

    It worked earlier, no problems no errors, and /rules command still works, but not /rules survival

    Found the problem
    1. if (args[0].equalsIgnoreCase("survival")) {
    2. Player player = (Player) sender;
    3. if (player.hasPermission("hammerfall.rules")) //<---- You forgot to put a "{"
    4. sender.sendMessage(config.getConfig().getString("survival-rules"));
    5. //<----- and here a "}" else {
    6. sender.sendMessage(ChatColor.DARK_RED
    7. + "You don't have permission to do this!");
    8. }
