Solved adding a level to a players total level..

Since xp didnt work i tried level didnt work either but the method and class are called upon..

Code:

    public static void Rankup(Player p) {
        int level = p.getLevel();
        p.setLevel(level + 1);
        if (Main.get().stats.getString(p.getUniqueId().toString() + ".rank") == null) {
            Main.get().stats.set(p.getUniqueId().toString() + ".rank", Main.get().ranks.getString("Ranks.0.name"));
            Main.get().saveStats();
        }
        int total;
        total = p.getLevel();
        if (Main.get().ranks.get("Ranks." + total) != null) {
            if (!Main.get().ranks.getString("Ranks." + total + ".name").equalsIgnoreCase(Main.get().stats.getString(p.getUniqueId() + ".rank"))) {
                String rank = Main.get().ranks.getString("Ranks." + total + ".name");
                Main.get().stats.set(p.getUniqueId().toString() + ".rank", rank);
                Main.get().saveStats();
                Main.get().sendConfigMessage(p, "rankup", rank);
            }
        }
    }
