OK, I'm opening a new topic on this. A few days ago I tried to upgrade automatically, using a plugin. That went wrong, so I finished it of manually. However, now I can't login to WordPress at all - in fact, if I try to access any wordpress-related files, it gives me a 404: take a look at http://ann.paperairplanes.nu/wordpress/wp-admin . It doesn't make sense - all my files are in perfect order, and are all there. Help?
