Item trader- u cant use it right now

Hi , i just started the game and since 2 days i get the notification "u cant use it right now" when i try to sell something .

I have nothing on item trader 0/10.
Is there a way to fix the Bug to use the item trader again?

You need to type /unlock 123456 or your 2nd password each time you log onto the char to be able to use it.
