Error attempting to sell
@Woolfiee: I recommend that you create a support ticket. It’s not likely an error with the trading post, since 100s of thousands of people are able to use the trading post successfully. I have spoken to a few players who had something that needed to be adjusted in their account in order to use the TP. Unfortunately, that seems to be the case for you, too.
@Fhey: I think your situation also falls into an account issue, too. So if you go another five days without a response, I recommend you add your ticket number to the 5+ days thread: https://forum-en.gw2archive.eu/forum/support/account/Tickets-for-Review-5-days-and-older-merged
