[FIXED]

For some reason it only will disable and not enable can anyone help?

Code:

package me.lively.BlockChanger;
 
    import java.util.ArrayList;
    import java.util.logging.Logger;

    import org.bukkit.ChatColor;
    import org.bukkit.command.Command;
    import org.bukkit.command.CommandSender;
    import org.bukkit.entity.Player;
    import org.bukkit.event.Event;
    import org.bukkit.plugin.PluginManager;
    import org.bukkit.plugin.java.JavaPlugin;

    public class BlockChanger extends JavaPlugin
    {

        private static final Logger log = Logger.getLogger("Minecrat");
        private final BlockChangerListener blockListener = new BlockChangerListener(this);
        public final ArrayList<Player> BlockChangerUsers = new ArrayList<Player>();

        @Override
        public void onEnable()
        {
            log.info("[BlockChanger] has been enabled!");
            PluginManager pm = getServer().getPluginManager();
            pm.registerEvent(Event.Type.BLOCK_DAMAGE, blockListener, Event.Priority.Normal, this);
        }

        @Override
        public void onDisable()
        {
            log.info("[BlockChanger] has been disabled!");
        }

        @Override
        public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)
        {
            if(commandLabel.equalsIgnoreCase("BlockChanger"))
                toggleBlockChanger(sender);

            return true;

        }

        private void toggleBlockChanger(CommandSender sender)
        {
            if( enabled((Player) sender) )
            {
                BlockChangerUsers.add((Player) sender);
                ((Player) sender).sendMessage(ChatColor.RED + "Lively made this plugin!");
            }
            else
            {
                BlockChangerUsers.remove((Player) sender);
                ((Player) sender).sendMessage(ChatColor.BLUE + "Livelys plugin is now disabled!");
            }
        }

        public boolean enabled(Player player)
        {
            return BlockChangerUsers.contains(player);
        }
 
    }
