I have made several posts in "Unpublish" mode. It took me all day yesterday, but lo and behold, i looked at my metrics and i still get many visits on the "unpublished" posts so i investigate and followed the URL, and voila! the supposed unpublished posts are still published! wtf!!! can wordpress do something about these things. it is frustrating.
Also, if one tries to mass delete posts, it returns an error message instead., so that the only means to delete a post is to go and open the posts and delete each and everyone of them, a very tedious task indeed.. Another wtf!!
