Canceling Command (Any Help <-- :D)

Hi, I'm writing a plugin to cancel the command to another plugin... I can't seem to find the error in my code but I'm getting this error.

Code:

[00:13:25] [Server thread/INFO]: JasonBourne685 issued server command: /deop JasonBourne685
[00:13:25] [Server thread/ERROR]: Could not pass event PlayerCommandPreprocessEvent to ConsoleOnlyCommands v1.0

Thanks so much for any help

 

AXCoding plugin is null, you never give it a value.
Also, look up dependency injection. Don't use static if you don't understand how it works.

 

xTigerRebornx Wow, I failed.. Thanks for the advice, I will be sure to research static .

 

Yes, don't watch BCBroz.
