Hi, I followed the instructions here: http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory my blog was already in it's own directory /blog/ so I followed the instructions so it would be accesible from the root directory without moving it. However now when I try to preview a post I'm writing I get a 404 error.
I've tried using a different browser, clearing browser cache, using the default theme, and deactivating plugins.
Any help would be much appreciated! Thanks.
