Hi,
Even when I give permission, shows the message: You do not have permission to use this kit.
What can I do?

Follow #1 please.

This ticket isn't closed, so help? There is NOTHING else wrong with the plugin except for the fact that when users right click the sign, it says "User doesn't have permission".

I am using GroupManager, and gave the groups these possible nodes:
- BattleKits.use.archer
- BattleKits.use.Archer
- BattleKits.sign.use
- BattleKits.kit.Archer
- BattleKits.kit.archer

I tried Uppercase and Lowercase, and they still won't work, thanks!

battlekits.sign.use and battlekits.use.kitname are the only permissions they should need. "User doesn't have permission." isn't an error BattleKits gives. BattleKits would send a "You don't have permission to use kit signs" error or a "You do not have permission to use this kit!" error.
