Hello. I installed vanish to my server and I am trying to do /vanish toggle nopickup command. I've searched that I need bpermissions plugin to do it but it still gives me the "You can't toggle that" error.
I don't know how to set up the permissions, if someone can help me with a noob guide for Bpermissions I would want to know it.
Thank you very much in advance.

Read the documentation on bPermissions.
