    all /ajb commands aren't working for me in latest version. Using spigot for 1.7.10.

    I really need to whitelist some players :S Please fix or tell me how to whitelist >_<

    PD: No console output when executinc commands. Even console does not recognise the whitelist commands and asks me to use /help.
