Farmville market on facebook

I play farmville on face, previously it was ok. I could play it. But I am unable to sell anything in my gift box or on my farm, I'm unable to redeem my spring eggs too. When ever I try to do any of these nothing happens. Also I cant delete any farm unwanted.

Now a new problem has added , I cant buy anything. my market doesnt open. Can someone help me out pls.
