This looks to be an issue with vault. Are you running vault and if your not makesure vault is set to false in itemjoins config.yml

Can you post your items and config.yml in a pastebin.com send it please?

Ok, I think my vault is broken because some other plugins are not sensing it either. Have disabled it and it is now working. Thanks!

Sweet, let me know if you ever need help with anything else.
