Solved Problems with enchantments in Essentials

When I do /I 278 1 efficiency:1 It does nothing not a message pops up and I don't even get the pick
I was originally trying to do this in kits but the same exact thing happens

Installed plugins are: CoreProtect, WorldEdit, CombatLog, Essentials, EssentialsChat, GroupManager, Treefarm, Spawner, BuycraftX, Vault, EssentialsSpawn, WorldGuard, CItizens

Config.yml is: http://pastebin.com/aUpArkfS

Error in console: http://pastebin.com/FZFFwPS4

Much appreciated for response!

Solved it: It was just a bad version of Essentials I've got EssentialsX now and I just needed to switch out the jar files and it all worked
