    HungerCraftNL You could just use this method to enable colors in config
    Code:java
    1. String bcPrefix = ChatColor.translateAlternateColorCodes('&', plugin.getConfig().getString("Prefix"));

    If 'Prefix' doesn't exist in your config, it bcPrefix will be null, so using .replaceAll() on null will throw that NPE :)
    (instead of replacing all & with §, you should use this (after checking bcPrefix isn't null that is): )
    Code:
    bcPrefix = ChatColor.translateAlternateColorCodes('&', bcPrefix);

    But it don't works for the StringBuilder right?

    And even with the new codes ( translateAlternateColorCodes(blabla)) do I've got a error:

    HungerCraftNL Do you have something like this in config ?
    Code:
    Prefix: &3[RandomPrefix]
    because I can't see any other way why it would be throwing a null pointer exception

    Look at the JavaDocs for getString():
    That's why you're getting the NullPointerException at line 43

    And the ArrayIndexOutOfBoundsException is because you're accessing args[0] without checking that args is at least 1 long :)
