Having a problem updating the price on customers ad's
So I've been trying to update some ad's that some of the customers on my site listed, because they made an error. However, its not making the change. I tried doing both, updating just the specific price and clicking update on the left of it. Also updating the whole ad listing. Neither works. It use to work without any problem for me. Can someone help?
