Status uopdate thing gone

I was going to update my status when the box where you type it in and it says "what's on your mind?" was gone. I really need help with it. I tried restarting my computer and getting javascript on it (which it already had on it). I don't know why it is gone and I've tried everything. I can't get any screenshots because my buttons that let me get a screenshot aren't working. I NEED help!
