Hey...
You cant just send error , you need to tell when you got that ? did you get it before ? 
Was you adding items in config in your blacklist items ?
On first i think your config is corupted , yours :
"BlacklistedItems": [
    {
      "ItemId": 550753330,
      "SkinId": 0
    }
  ],
Send me your config 

my config

  ],
  "CustomItems": [
    {
      "ItemId": -1707425764,
      "SkinId": 3122790562,
      "DisplayName": ""
    }
  ],
  "BlacklistedItems": [
    {
      "ItemId": 550753330,
      "SkinId": 0
    }
  ],
  "Version": {
    "Major": 1,
    "Minor": 0,
    "Patch": 1
  }
}

I don't know what happened, but it showed up in the Rcon logs.

OK ..so you didnt change your config ..
You didnt change anything in code of plugin? 
That OpenBuyUI shoud open buy panel list ... 
Just try to press that button again ,and say do you get again that error 

I haven't changed any plugins either.


Every time I press the Buy button, the following error message appears:

Oke... 
When you press that buy button does it open buy panel ?
Did you try to reload plugin ?

The purchase panel does not open.
Reloading the plugin returned it to normal.

ok ...
I tryed to reproduce that error now on many ways ..didnt get it at all ..
So not sure why did you get it ...
So after reload all working fine ? 

Everything works fine.
I'm trying to reproduce it here but it doesn't work.

OK Great then !
Iam felling like config file didnt load up correcty , maybe of unloading reloading something , wiping , restarting ... Dont know ..

Changed Status from Pending to Can't Reproduce
