Steps I took

I loaded the plugin & started the server with no errors. I then went to the server consol & did the following

> oxide.grant user VsUK backpacks.use.large
Player 'VsUK (76561197962548959)' granted permission 'backpacks.use.large'
> oxide.grant user VsUK backpacks.use.medium
Player 'VsUK (76561197962548959)' granted permission 'backpacks.use.medium'
> oxide.grant user VsUK backpacks.use.small
Player 'VsUK(76561197962548959)' granted permission 'backpacks.use.small'
> oxide.reload Backpacks
Unloaded plugin Backpacks v2.1.7 by LaserHydra
Loaded plugin Backpacks v2.1.7 by LaserHydra

I then in game put /backpack & I got. You do not have permission to use this command

Can someone tell me where I'm going wrong?

I even gave permission to groups default & admin succesfully but no luck when logged in as admin either.

Thanks in advance!
