Potrzebne jest źródło, żeby powiedzieć coś więcej odnośnie do błędu. Gdzieś w onClickMain jakiś getter (strzelam, że pewnie getInventory lub podobny) zwraca nulla.

Polecam przeczytanie sobie poradnika o odczytywaniu błędu, dobrze jest to umieć =)

Tak wyglądaa kod w funkcji "onClickMain"

public class InventoryClickListener implements Listener {
    @SuppressWarnings("deprecation")
	@EventHandler
    public void onClickMain(InventoryClickEvent event) {
        Player p = (Player) event.getWhoClicked();
        if (ChatUtil.fixColor(Config.NAME).equalsIgnoreCase(event.getClickedInventory().getName())) {
            event.setCancelled(true);
            if (event.getSlot() == Config.SPEED_SLOT) {
                if (p.getInventory().containsAtLeast(new ItemStack(Material.getMaterial(Config.SPEED_CURRENCY)), Config.SPEED_AMOUNT)) {
                    p.getInventory().removeItem(new ItemStack(Material.getMaterial(Config.SPEED_CURRENCY), Config.SPEED_AMOUNT));

Zgodnie z kodem, który wkleiłeś 20 linia to:

ChatUtil.sendMessage(p, Config.SPEED_LACK);

Nie widzę, żeby coś tutaj mogło wyrzucić NPE.

To może policz linijki u siebie w kodzie?

20 linijka to if (ChatUtil.fixColor(Config.NAME).equalsIgnoreCase(event.getClickedInventory().getName())) {

Jeśli gracz kliknie poza inventory - getClickedInventory() zwróci null I najlepiej wrzucaj kod np. na pastebin.com
