Bukkit

Non-opped players are not able to use buy signs for certain items. They can use sell signs just fine. I have checked that they have the correct permission node (ChestShop.shop.*). I am using version 3.8.13 on Spigot 1.11.

For example, they can buy dyes just fine, but they cannot buy Grass Blocks or Redstone Comparators.

They can left click the buy sign to get a you can't sell here message, but right clicking it does nothing whatsoever.

Please provide some more information like your config, your permissions, the setup of the shop, etc.

Closed the issue due to no new information. Most likely a permission or a setup error.
