Appears RED when I do /plugins (Bukkit)

Using Vault, WorldEdit, WorldGuard, NametagEdit & Essentials

Any errors in console on startup?

READ THIS: You are running with the incorrect version of PEX for your MC version. Remember: use 1.22.x for 1.7.9+, and 1.23.x for 1.8.x

However the verision I am using is; PermissionsEx-1.22.10.jar

EDIT: Using 1.12

Use version 1.23.4

Thanks! Works like a treat

Please lock thread

that's actually impressive... using an even older yet equally unsupported version of the plugin
