Any help apreciated! I don't understand "File cannot be null" It wont even tell me the file name D:

 

It is saying that your config is null. You are using a null object, just set the variable in the onenable.

Ok thanks! Didn't realise

LegoPal92
Still doesn't work :/
Code:

Code:java

    getConfig().set("Enabler", 1);
        saveConfig();
 

I added that to the onEnable^^

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

 

What is that supposed to do? All that does is set the line: Enabler: 1 in the config. What you need to do is have your variable initialized in your config.

I fixed it
It was to do with my Eclipse not exporting properly!
