CHMOD Problems

No matter what I try, I can not CHMOD my files. It just started to do this. I use to be able to CHMOD my files but now I can not. And there is no error or any other problem to say that it isn't CHMODing. In fact, I keep getting the same thing as I use to get. As if the file actually CHMODed but it didn't when I refreshed the page.

What did the status message say?? Did you advise your host? I doubt this is a sftp problem.
