Minecraft Version: 12.2.2
ChestShop Version: 3.9.2
iConomy VersionL 5.08 (Towny version)

Server Setup: I am running a Cat Server so I can use both Forge and Bukkit plugins on the same server. I am also using Towny Advanced (v 93)

Here is my sign configuration

AdminShop (or "Admin Shop")
1
B 1:S 1 (or "B 1: 1 S")
?

Expected Behavior:
I right click on the sign with the item I want the shop to sell (e.g. bed) and the shop now sells bed to players.

Actual behavior:
I right click on the sign with the bed and I get the error: "You don't have permission to do that."

Additional information:
I am Opped on the server. Normal player chest shops work just fine. If you have a chest nearby you can buy and sell items. Only the admin shop doesn't work. If I manually type in "Bed" instead of ? the shop just doesn't work at all.

I am using LuckPerm and ForgeEssentials but in a test environment I wiped away both of these permission mods and made sure I was opped and received the same error, so I think it's a permission issue with just the plugin. I also tried manually adding the permission chestshop.admin to my player and that did not work as well.

Any help would be appreciated.

Yeah that issue is from any shop whether it's admin or player. I also updated to latest vault version but that didn't fix anything. After this testing I installed MIG, which is another shop mod and it worked it just fine both buying and selling so I'm not sure what's up.

Did the player re-create the player shop themselves or did you do that for them? (Make sure it was the player themselves without writing the name on it so that we can 100% sure that the auto-generated name doesn't work)

Also please provide your log and config file.

I tried the latest development build from here. It did resolve the permissions issue but not every time someone tries to buy or sell from any shop, there is a "player not found" error.

Hm, can you test it it works after a player shop is re-created?
