Solved PEX isn't working for me

Okay, I have deleted and reinstalled pex multiple times, have edited the permissions multiple times and now I can't seem to get PEX to allow me to set people to groups from the console or in game. (I apologize for the mess ahead of time!)
This is what I had before:

Code:

groups:
Default:
options:
default: true
permissions:
- essentials.back
- essentials.suicide
- essentials.home
- essentials.sethome
- essentials.spawn
- multiverse.portal.access.*
- essentials.mail.send

- essentials.msg
- essentials.tpaccept
- essentials.tpa
Admin:
options:
prefix: '&0(&4Admin&0)&7 '
permissions:
- warpportal.admin
- griefprevention.*
- essentials.*
- worldedit.*
- modifyworld.*
- permissions.*
- multiverse.portal.access.*
VIP:
options:

permissions:

Beta-Tester:

permissions:

For a little while, I could edit the groups with the short guide Deonasoto provided but it isn't working. Can somebody please help me figure out what I'm doing wrong/ how I messed it up?

Full server log as in, the console logs?

 

I just found it, sorry about that. http://pastebin.com/smNFEuFr

 

If I try to do: pex user (myname) group set owner it doesnt show that i have been placed in that group , as well as if i type /pl, a whole list of plugins comes up and when it does, permissions ex is in red unlike the rest.

So, I turned on the whitelist, uninstalled PEX, and shut down the server for 5 mins. Found that the last time I uninstalled/reinstalled it was the wrong plugin. So I re-downloaded the correct plugin, turned off whitelist and restarted the server and now it's doing fine. Thank you for your help, I wish i would have caught my mistake before looking like a dummy.
