Exactly the same problem for me as the OP, and only started very recently. Issue exists for me in IE8 (Blank Screen) after entering username and password, and in Firefox 21.0 (no black screen but the login page just seems to reload).
OK so I got an in game email telling me its published, Yay! Or so I thought. How on earth am I meant to find it - there must be literally hundreds if not thousands of new ones that appeared, and under the "Review tab" (assuming that's where I should look) there doesn't appear to be any search filters?
Exactly what I have, and yet I have seen other quests with a date more recent than mine in the list. Frustrating! I've never actually managed to publish anything - do you get an in game email when its ready or something, to save me checking constantly?
