Unable to sell in AH or trade

Whenever I try to sell items in the AH or trade the game responds with something like "You are unable to do that at the moment".

The info about the 2nd password says "Justac won’t force players to set their 2ndpassword, it’s a personal choice." so not having a 2nd password shouldnt be the problem.

What else would caise the issue?

We set default password to all accounts now. I will fix description, it was copied from old forum.

I am having the same issue. Not sure how to fix it. I had sold some items on the AH 2 days ago but now i get the same message that its not allowed at the moment

the default 2nd pawword is set to every player.
so u need to type /unlock 123456

if u arent able to see ur items in ur sell list, u need to restart ur client.
