Whenever I go to my profile it requires me to sign in even though I am signed in. After I sign in it goes back to my profile and within seconds forces me to the sign in page again.

I think it has to do with the selling or trading lists that have been recently updated, but I cannot be sure.

I'm having the same issue.

Could you please tell us which browser you are using?

Found it, seems to be happening on old IE & some versions of Safari browsers.

Should be fixed now.

Works great now. Thanks!

Yep, works great for me too.
