Problem/Bug Autorank and PEX problem on Madpack 2 Server running Cauldron

As you can see from the title, I have trouble with Autorank in my Madpack 2 server which is running Cauldron. I know, Cauldron isn't exactly Bukkit, but, it is close enough.


My list of plugins are: Plugins (16): WorldEdit, Essentials, EssentialsChat, PermissionsEx, RandomTeleport, WorldBorder, Vault, Votifier, EssentialsSpawn, WorldGuard, Multiverse-Core, EnjinMinecraftPlugin, KitAdder, EssentialsProtect, Autorank, GriefPrevention


There is one problem with /plugins: Permissions EX is red, I don't know what that means either.


So, now, to the problem. When I do a command using Autorank, for example, "/ar check" I get an error:

Console Error:

Thanks to anyone who can help me fix this,
