Hi, im greeves12 I have a minecraft bukkit server. I have downloaded vault so I could be able to use some plugins. But the weirdest thing happened! When I logged it said [L] 0 [Owner][Owner] greeves12. Which is weird since before I enabled vault it was normal like [Owner] greeves12. I really need help, thanks.

I think you need to supply more information, such as which permission plugin, it's version, bukkit server version, just general information to help the devs help you.

Just noticed the title said groupmanager ;) oops

Vault doesn't do anything with chat, you have another plugin that is enabling features when it sees vault installed.
