My directory structure is as follows:
/blog/wordpress/
/blog/wp-content/
/blog/index.php
/blog/wp-config.php
I know this setup will work, but it looks like the install process doesn't.
If I go to http://www.mydomain.com/blog/ to start the install, I get the following 404:
The requested URL /blog/wp-admin/install.php was not found on this server.
The correct url should of course be /blog/wordpress/wp-admin/install.php
