If you know the answer to this, please help out. THANKS!!!

 

Change

Code:

spawnsFile = new File(getDataFolder(), "spawns.yml");

to:

Code:

File spawnsFile = new File(getDataFolder(), "spawns.yml");

and remove

Code:

File spawnsFile = null;

 

BungeeTheCookie You might have forgotten to make sure the folder inside your plugins folder exists as well.

Code:java

if (!p.getDataFolder().exists()) p.getDataFolder().mkdir();

 

SkillSam calebbfmv
I tried both of your methods, and neither work.

It is also giving me the same error btw

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@BungeeTheCookie:

your problem is that the variable plugin in ConfigManager is never initialized, because only the default constructor (with no parameters) is called...

 

Why would you set up your config manager part object and part singleton?
