Background: I have 3 blogs running via WP.org under a single domain.
I also have had a WP.com blog that I successfully imported (using Aaron Brazell's plugin) to a new WP.org blog also under the same domain.
The domain is cranialcavity.net. The migrated blog should be cranialcavity.net/motorsports and that is how it's displayed on the options page in the "WordPress address (URI)" and "Blog address (URI)" blocks.
However if you call up that url it displays the index page of the base url, cranialcavity.net which is one of the other blogs on the domain.
I attempted to change the url in the "WordPress address (URI)" block to read cranialcavity.net/motorsports/index.php and after the change it bounces you to the correct blog but it contains no styling just plain text.
I have since emptied the database and reinstalled and await a possible solution to this problem.
