The players have discovered that it is impossible to buy industrial.wall.light.(all colors) I was creating a new one and the same thing, in the chat he says you can't buy this item.

Hey! So industrial wall lights are actually DLC items in Rust, thats why the shop blocks the purchase. The plugin checks if the player owns the DLC before letting them buy it. You can bypass this by giving players the permission "shop.bypass.dlc". Run oxide.grant group default shop.bypass.dlc and itll let everyone buy DLC items regardless of ownership.

Thanks for the clarification, I think it's not worth doing this, Facepunch has banned the DLS page
