    Either config is null, or your string is null when you get it from the config

    Are you sure you did not forget to save the config after adding the user into the config?

    Do you know how casting works? Because you're currently casting getConfig with bow, wich makes literally no sense.
    And please, post a screenshot from your whole screen, while you're looking at the config (I need the whole screen)

    Edit: wait wait wait, why do you have that getConfig method in the class? Of course it throws a nullpointerexception, getConfig always returns a null

    Edit2.: I see, you wanted to use it, and it howed an error, and you pressed the firsg button availabke in eclipse, you need an instance of the main class, and then do instance.getConfig(), and remove that getConfig method

    The best way is to learn java. But you need to create a Main type field and use the cobstructor, to pass an instance of the main class, by using the this keyword, and in the constructor set the instance to the main instance you got

    @mcdorli
    With the forums being the piece of crap they are, I'll agree.
    Because the forum developers didn't set a fixed size for ad elements, the page jumps around all the time while it's loading, and constantly closes the keyboard if you try to type.
    Do you have these issues too? Because they make it a nightmare to comment while on any portable device
