DevManABCD Try replacing

Code:java

line = line.replaceAll("&", "§");

with:

Code:java

line.replaceAll("&", "§");

 

sipsi133 Still doesn't work, same errors.

 

DevManABCD I think sipsi133 meant replace this:

Code:java

line = line.replaceAll("&", "§");

with this:

Code:java

line = line.replaceAll('&', '§');

 

It's a NullPointer, the issue is that the String "line" is unset (null),
This line:

Code:java

String line = (this.plugin.configManager.JoinMotd);

isn't retrieving the object, make sure that it is set.

 

Its set and working, sending me a message.

 

Ensure that configManager is set then, you should think about changing the way you access all of your data. It appears you've set everything to public which is horrendous in terms of logic and validation.

Inside your JavaPlugin class, you should implement getters and setters of object.
