Getting a null pointer exception at https://github.com/MilkBowl/Vault/blob/master/src/net/milkbowl/vault/permission/plugins/Permission_GroupManager.java#L379

need more information that just you're getting an NPE here. What versions of each plugin you're using, the full stacktrace message, what triggered the error etc.

Closing due to lack of response. If you can provide more information please do re-open.
