Market and trading problem

"Hi, does anyone else have a problem with the in-game market or is it just me? It says that the items I’m looking for can’t be found, and on the trade site when I click 'go to hideout' it says I need to be in the same league as the player who is selling. Can anyone help, or is this a known issue at the moment?"

You need to make sure you have the correct league selected on the trade site.

If you are in standard and try to trade with someone in abyss league it wont work. Same goes for hardcore and softcore leagues. Trying to trade from softcore abyss to hardcore abyss will get you the same error.
