Config not saving anything anymore

Hi!
My config is no longer saving anything, it used to be working just fine but now it isn't. I am getting NPE's on basically everything that involves a config. Thanks

Code:

@Adrian Pasternak
You are not setting the config. Look what config is equal to. You never set it to anyhting, so the config is null. Before doing anything to the config, set config equal to getConfig in the onEnable.

 

fileconfiguration.save(file)

then try and catch

 

I did set the config

Code:

config = (YamlConfiguration) getConfig();

 

@Adrian Pasternak
But that is not in the onEnable. The onEnable references the config, so you need to set the config inside the onEnable.

 

Just saying consider, using uuid instead og playername

I did this as well,

Code:

public void onEnable(){
        for(Player p : Bukkit.getServer().getOnlinePlayers()){
            if(!config.contains(p.getName().toLowerCase())){

            config.createSection("refers." + p.getPlayer().getName().toLowerCase());
            saveConfig();
        }
    }


        Bukkit.getPluginManager().registerEvents(this, this);
        if (!setupEconomy() ) {
            log.severe(String.format("[%s] - Disabled due to no Vault dependency found!", getDescription().getName()));
            getServer().getPluginManager().disablePlugin(this);
            return;
        }
        config = (YamlConfiguration) getConfig(); 
        this.loadConfig(); 
        this.saveDefaultConfig();
        }

That is my entire onEnable,

 

You are referencing the config two lines into the onEnable. That means the config has to be set before this line. To fix this, either:

• Add "config=getConfig()" directly under the onEnable.
• change "YamlConfiguration config;" to "YamlConfiguration config = getConfig();"
