FaCEBOOK MarketPlace, cannot place ads

Is this some type of soft ban. I was using MP just fine for 3 weeks to sell 10 items furniture and now i cannot post or edit post, just takes me blank type screen that is unresponsive, and that particular Safari screen locks up. I can search marketplace just fine. My account is 3 years old with light use and connected to my instagram. The only thing I can think of is a buyer is irritated would nt sell something to her.
