Hey,

i´ve got a problem with my plugin...
When i start my server with the plugin, i get an error, like this:

Code:

17:22:26 [SEVERE] Error occurred while enabling Tutorial v0.4 (Is it up to date?
): null
java.lang.NullPointerException

Don´t know what to do... It did well yesterday, but today i added some configurabel messages and now...

Help please... :/

EDIT: Here is the code of the main class.

 

You only define loots1 as a string array. You have to explicit the declaration line,
String [] msg = new String[10], loots1 = new String[10];

 

Yep, youre right, noticed that 5 minutes ago
Anyway, very much thanks
