    tangster132 " at potato.kits.Menu.show(Menu.java:243) "

    tangster132 which is just p.openInventory(inv);

    PotatoLol12321 There is nothing null about the inventory, because there is no inventory. That is to say, the variable inv is pointing to null i.e. is a null pointer.

    I can't tell from the code lol. Just check whenever you call your show() method if anything could be null.

    tangster132 I'm not sure what's making it null, it works when I don't pull the strings from the config, but when I print out the strings, it's the ones from the config, but it's not creating the inventory I guess... not sure what I'm doing wrong.

    In the listener class, Try removing the null part from creating the inv, Might fix the "null" exception

    Code:java
    1.  if(sender instanceof Player){
    2. Player player = (Player) sender;
    3. if(sender instanceof Player){
    4. menu.show(player);
    5. }
    6. }


    Change that to this:
    Code:java
    1.             if(sender instanceof Player){
    2.             Player player = (Player) sender;
    3.                     menu.show(player);
    4.             }

    PotatoLol12321 Can I see line 152 of Menu? I know you posted your code, but the numbering could be off.

    EDIT: And you really do not need createItem, createItem2, createItem3..., just call createItem as many times as you need :/

    2. if (!e.getInventory().getName().equalsIgnoreCase(inv.getName())) return;
    3.

    PotatoLol12321 That's fine. Thanks for showing me the new one, because I would've said inv.getName() is null. :p

    As for your error, I think the code in the OP is different than your current code. Could you post the new code (Main plugin & listener).

    If this issue is happening when the item is clicked make sure you add this line of code to the EventInventoryClick:

    if (event.getCurrentItem() == null) return;

    Okay I'll look into it

    Instead of declaring Inventory inv;
    in the Listeners class, try declaring it as a menu.

    declare it as

    final Inventory inv = Bukkit.getServer().createInventory(null, 9, MenuInv.config.getString("GUIName")).replace('&', '§');
