Solved Economy Plugins Problem

On my 1.8 Server, all economy plugins come up with an error message when I start the server with a spam of lines saying
[20:15:55 INFO]: ItemDEF: null

I tried playing through the error but no commands work anymore. I run
Vault, CobraKits, WorldEdit, WorldGuard, bPermissions, CommandSigns, GUIShop, MPK, MultiWorld, PlayerVaults, CrazyAuctions, EasyWarp.

If any other info needs to be posted just reply.
Thank You.

 

It's Really hard to get it because once the null thing comes up I can't move my console up. I'll try though.

Being Able to look through the log I think I found the problem. I'll say if not.

I found the problem! Thank you for your help though!
For anyone with the same problem, GUI Shop caused my problem
