@Kamus My Gwibber is its latest version. I don't know why: after I uninstall-ed the program and reinstalled it, comments can be posted successfully! However I then got problems mentioned by many others that I have to wait for a looooong time to actually see latest comments inside Gwibber. But the comments are there in Facebook.
So anyway this bug is solved!
