Bukkit

What is the issue?

The nodes are not working

Please provide any additional information below.

I worked for few days, many hours with this plugin so far. And I love it! Only thing is that it seems like only operators can use this.
I tried to allow the permissions to everyone but I just got message saying that it's an invalid permission.
Then I tried to look for the permissions thru permission finder and it didn't found any nodes for this plugin.

So I would love to know if there's any way to add permission to this on my own or is there any other way to allow other players to open these lootboxes.

Thanks Lasuuri
