Bukkit

SWatchdog version:
Bukkit version: 1.6.2
Are you using tekkit? no
What is the problem?
I installed the plugins and typed /whelp 10 to try and enable the use of the wand. I followed the instructions and it responded with "you don't have proper permissions...". So I didn't think much of it, I just turned the server off and went into the config and set usetools to true. I started the server back up, grabbed a stick, and right clicked a block. Nada. I then looked at the console to find a "severe" warning, and sure enough, a big ol' severe code was right in front of me. If I recall correctly, this happened to me on earlier versions as well, so its not new. I really like that magic wand and would be much obliged if you could do something about it!

Please paste an error-log:
