Permission Does not exist

Just wondering if this plugin is till working. I downloaded newest version and uploaded to my plugin oxide file... Like I have all my other plugins. Restarted my server and it created a config file. I enter oxide.grant group default buildingskins.use and I get permission buildingskins.use doesnt exist. Any help would be appreciated

Installing the image library dependency fixes the error. Install dependencies when a plugin requires them.

Actually. What I said may not solve for everyone the error that was reported there and which also caused the permissions issue for me pointed here. @BillCosby

So, it would appear I am not the only one.
I as well am receiving the "Do Not Have Permission" in game. using /bskin command
