    You tried what exacly ?

    "config" is obviously null since you didn't asign it to anything.

    You don't even need that by the way, just use getConfig() directly, it won't re-read the config every time you call it, it's optimized nicely.

    Also, you might want to use ChatColor.translate....() to convert color codes.

    The config.yml file has nothing to do with that error on that line, the only thing that can trigger NPE at that exact line is the "config" pointer.
    If you get null back from the getString() it will asign the variable to null, why would that give a NPE ?

    Digi XDemonic25 it's because he never actually asigned the variable "config" he did FileConfiguration config = this.getConfig() he was supposed to do config = this.getConfig()

    xXMaTTHDXx we explained on what is wrong with your code it is
    because you never set your "config" variable you have to remove the FileConfiguration part from your onEnable method

import java.util.logging.Logger;
 
import org.bukkit.ChatColor;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;
 
public class SweetLogin extends JavaPlugin implements Listener{
    public static SweetLogin plugin;
    public    final Logger logger = Logger.getLogger("Minecraft");
    public FileConfiguration config;
   
    @Override
    public void onDisable(){
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() +"version" + pdfFile.getVersion() + "is now disabled");
            }
       
   
   
    @Override
    public void onEnable(){
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() +"version" + pdfFile.getVersion() + "is now enabled");
        getServer().getPluginManager().registerEvents(this, this);
        config = this.getConfig();
        config.get("Messages.path");
        config.addDefault(" Messages", " Your Message Here.");
        config.get("Color.path");
        config.addDefault("Color", "&");
        getConfig().options().copyDefaults(true);
        saveDefaultConfig();
       
       
    }
   
    @EventHandler
    public void onJoin(PlayerJoinEvent event)
    {
        String loginColor = getConfig().getString("Color.path");
        String loginMessage = getConfig().getString("Messages.path");
        event.setJoinMessage(loginColor + event.getPlayer().getName() + loginMessage);
        if(loginColor.contains("&0")){
            loginColor.equals(ChatColor.BLACK);
        }
        if(loginColor.contains("&1")){
            loginColor.equals(ChatColor.DARK_BLUE);
        }
        if(loginColor.contains("&2")){
            loginColor.equals(ChatColor.DARK_GREEN);
        }
        if(loginColor.contains("&3")){
            loginColor.equals(ChatColor.DARK_AQUA);
        }
        if(loginColor.contains("&4")){
            loginColor.equals(ChatColor.DARK_RED);
        }
        if(loginColor.contains("&5")){
            loginColor.equals(ChatColor.DARK_PURPLE);
        }
        if(loginColor.contains("&6")){
            loginColor.equals(ChatColor.GOLD);
        }
        if(loginColor.contains("&7")){
            loginColor.equals(ChatColor.GRAY);
        }
        if(loginColor.contains("&8")){
            loginColor.equals(ChatColor.DARK_GRAY);
        }
        if(loginColor.contains("&9")){
            loginColor.equals(ChatColor.BLUE);
        }
        if(loginColor.contains("&a")){
            loginColor.equals(ChatColor.GREEN);
        }
        if(loginColor.contains("&b")){
            loginColor.equals(ChatColor.AQUA);
        }
        if(loginColor.contains("&c")){
            loginColor.equals(ChatColor.RED);
        }
        if(loginColor.contains("&d")){
            loginColor.equals(ChatColor.LIGHT_PURPLE);
        }
        if(loginColor.contains("&e")){
            loginColor.equals(ChatColor.YELLOW);
        }
        if(loginColor.contains("&f")){
            loginColor.equals(ChatColor.WHITE);
        }
