Line 24 is:
PluginManager pm = this.getServer().getPluginManager();


Any idea what could cause this? This is 806 i believe

 

can you post the code, or at least some of it, because there could actually be many reasons why this error occurred, and recently there was another post about the same error.

 

What part do youw ant to see? do you have teamviewer? its a rather large source.

 

I do not have teamveiwer, could you just post like up to line 30 on iWarning?

 

Code:

package com.elitecraft.cronikk.iwarning;

import java.io.File;
import java.io.IOException;
import java.util.logging.Logger;

import org.bukkit.event.Event;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.util.config.Configuration;
import com.alta189.sqllitelib.*;

import com.nijiko.permissions.PermissionHandler;
import com.nijikokun.bukkit.Permissions.Permissions;
 
public class iWarning extends JavaPlugin{
    Logger log = Logger.getLogger("Minecraft");
    String mainDirectory = "plugins/iWarning";
    public File pFolder = new File("plugins/iWarning");
    public static PermissionHandler permissionHandler;
    PluginManager pm = this.getServer().getPluginManager();
    public SettingsHandler settings = new SettingsHandler("settings.properties", "plugins/iWarning/settings.properties");
    public sqlCore dbManage;
    public iWarningFunctions functions = new iWarningFunctions(this);
    public iWarningBanHandler banHandler = new iWarningBanHandler(this);
    

 

you should have the getPluginManager in the on enable, have a non set PluginManager pm; and then pm=getServer().getPluginManager();

 

I just put the whole line in the onEnable() thank you! Now works!

 

welcome
