I have this in my config:

  "Unallowed container": [
    "box.wooden.large",
    "box.wooden",
    "coffin.storage",
    "small.stash",
    "locker",
    "storage_barrel_c",
    "storage_barrel_b",
    "storage_barrel_a"
  ]​

Try
"storage.barrel.c", "storage.barrel.b", "storage.barrel.a"

omegablue

Try
"storage.barrel.c", "storage.barrel.b", "storage.barrel.a"

Ok, that fixes the barrels but I can still put food into the small wooden box.

You are right. Small box and stash don´t work for me too. The author should take a look at this.

Stash worked for me. Only the small box was the problem in my case.

Hello,

To make an easier job for the admin, I updated the plugin to include a command (/fdebug)
This command will allow you, as admin, to enable the debug mode.
The debug mode will give you the container name once you are trying to put food inside storage.
