I also have my wordpress installed in a different directory than my blog, and I also am experiencing this error.
I am also having this problem when, for example, I try to change the url an image in the gallery points to. This works if I insert the image, but if I attempt to save and then insert the gallery, all changes are lost when I save.
I’m also having this problem, but I haven’t done anything other than install WordPress. My post appears once it’s posted, but in the preview it says
“Not Found
Sorry, but you are looking for something that isn’t here.”
