Re: WordPress hosed
laran: that is the proper behaviour for published and unpublished draft or future posts in WordPress. When you are logged in, you can view them. When you are not logged in, you will get a 404 if you try to view one of those pages you could previously view.
If it possible you gave yourself more power when resetting the permissions? If you had author or contributor status in WordPress before, and now you have editor or administrator, it’s possible you are seeing things now that you could not see before.
But, in my experience, that’s the way WordPress works. If you are logged in and have permission, and the URL, you can view unpublished posts. When you are not logged in, you can’t, by design.
