"An internal error occurred while attempting to perform this command"

Hello, I've been having a problem with my server and it not letting me use commands in-game.
I get a error saying "An internal error occurred while attempting to perform this command".
The server is version 1.2.5 running on CraftBukkit++ (correct versions I believe)

My plugins are as follows.

Admin Status
Chat Manager
Command book
Essentials
Essentials Chat
Essentials Protect
Essentials Spawn
Essentials GeoIP
Essentials XMPP
Essentials Group Bridge
Essentials Group Manager
False Book
Mob Disguise
Modify World
Permissions Ex
Plugin Metrics
Permissions
Super Perms-Bridge
Ore Obfuscation
Simple Jail
Super Log
World Guard
World Edit

I have included a log for when I started up my server as it was too big to paste as code on here and it would freeze my Google Chrome.
I will also send my Permissions Ex (I've been using it). But the Permissions Ex will be in this post.

EDIT: The forum won't let me send the error report so ask and I'll tell you what it says near the error

OK sorry for double post but I have verified that Permissions Ex is the problem

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

 

fixed your permissions http://pastebin.com/8hukuHj8
but what permissions was that GM or PEX ? cause either way seams its wrong

choose pex or gm i would say try with pex than i could make your permissions work just fine

 

I am using PEX

EDIT: OMG thanks lol i could not get this to work and that worked. thanks so much

 

this is happening to me too
i really need help
