Bukkit

So... tried this plugin and it was not throwing any errors and commands work but people still able to hurt each other no matter what settings in config file I do. I set it up not to have pvp enabled to people by default. When checking status, it shows disabled for them for that world but they still able to hurt each other.
Just noticed that there is an error once in a while about not being able to pass event to citizens npc but not sure if thats what happens.
Have MCMMO and worldguard and multiverse on the server,
Again, it looks like its working and I can check status of users but they can still pvp no matter if its disabled or enabled on their own status
