File cannot be null error. Please help.

I have been searching for hours online, reaserching threads with the same error I am getting, and none of their fixes worked for me. Can anyone help me? Here is the stacktrace: http://gyazo.com/1b3dd9bb311f6220f6f388aee8332de9

Main class:

Code:

package me.mono;
 
import org.bukkit.Bukkit;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
import CommandHandlers.BanCommand;
import CommandHandlers.BanInfoCommand;
import CommandHandlers.BanLogin;
import CommandHandlers.CommandHandlerMethods;
import CommandHandlers.KickCommand;
import CommandHandlers.TempBanCommand;
import CommandHandlers.UnbanCommand;
 
public class Main extends JavaPlugin
{
  FileConfiguration config = getConfig();
 
 
  public void onEnable()
  {
    PluginManager pm = getServer().getPluginManager();
    pm.registerEvents(new BanLogin(this), this);
    getCommand("bh").setExecutor(new CommandHandlerMethods(this));
    getCommand("ban").setExecutor(new BanCommand(this));
    getCommand("banip").setExecutor(new BanCommand(this));
    getCommand("kick").setExecutor(new KickCommand(this));
    getCommand("tempban").setExecutor(new TempBanCommand(this));
    getCommand("baninfo").setExecutor(new BanInfoCommand(this));
    getCommand("unban").setExecutor(new UnbanCommand(this));
 
    this.config.addDefault("Banned.Player.BanType", "Perm ban!");
    this.config.addDefault("Banned.Player.BannedBy", "Monollyth");
    this.config.addDefault("Banned.Player.Reason", "Hacking");
    this.config.addDefault("Banned.Player.Length", "Permanent");
    this.config.addDefault("Kicked.Player.Times", Integer.valueOf(10));
 
    this.config.options().copyDefaults(false);
    saveConfig();
 
    Bukkit.getLogger().info(getName() + " has been enabled...");
  }
}

(It says the error is in the main class)

 

Do you have a config.yml in the same directory as the plugin.yml?

 

Nevermind guys, I fixed it myself, I never called a loadConfig() method in my main class.
