Cant sell items out of Premium stash tab

can somebdy help me fix this issue did i do something wrong whats going on ?

What do you mean by "Can't sell items out of your premium stash tab"?

People are not whispering you for the items?
Can you put a price on the items?
Can you list them on the trade?
Do they appear on the trade website?

You don't have to sell them, but put 1 item to test with a low price that will make it pop up at the top of the trade page to see if they appear.

do you have a (premium) stash tab if not this is your issue

I set everything on low like stellar amulet +7 on 1 exalt sapphire rings wtc and it didnt come up on the webside did the thing set price the same on evething got my box full and it didnt work at all. i fixed the game via steam rapair of broken files and it worked again
