All commands blocked due to error?

When I try to do a GroupManger command on my server, it says: All comands blocket due to an error. Check the log and than try a /manload. /manload doesn't work. Here's the log:

Also, here's the wepif.yml:

Code:

#
# WEPIF Configuration File
#
# This file handles permissions configuration for every plugin using WEPIF
#
# About editing this file:
# - DO NOT USE TABS. You MUST use spaces or Bukkit will complain. If
#  you use an editor like Notepad++ (recommended for Windows users), you
#  must configure it to "replace tabs with spaces." In Notepad++, this can
#  be changed in Settings > Preferences > Language Menu.
# - Don't get rid of the indents. They are indented so some entries are
#  in categories (like "enforce-single-session" is in the "protection"
#  category.
# - If you want to check the format of this file before putting it
#  into WEPIF, paste it into http://yaml-online-parser.appspot.com/
#  and see if it gives "ERROR:".
# - Lines starting with # are comments and so they are ignored.
#
# About Configuration Permissions
# - See http://wiki.sk89q.com/wiki/WorldEdit/Permissions/Bukkit
# - Now with multiworld support (see example)
