I had a feedback from a merchant today, that he looses the session after uploading a file and tradebit tells him: "you are not logged in"...
kind of strange and I was able to see the same message after uploading and leaving the computer for about 1 hour. After I came back and clicked, I saw the same.
Now we are not sure, if we forgot something... anyone with the same problem?
cheers,
puzzler
