I have reinstalled the plugins, I recently installed here as instructed. Although when I boot my server it is fine (without Vault) but when I install vault (the bukkit version) (its free) it comes up with Contact BlackSpigotMC 0x0. Even though the plugin is not from Blackspigot and their is no download for it here so I cannot upload a version from here to resolve the issue. @WifiSpy @8BiTH4cKeR
