The new version 1.5.7 of the plugin is broken. It does not seem to ignore slugs entered via the excludes field.
I have reverted the site I am working on back to version 1.5.6 of the plugin.
I tried moving wp-content and wp-config and that in principle seemed to work except that the themes could no longer use their stylesheets and images. I guess this would also affect plugins that contain their own stylesheets and graphics.
The solution for accessing css and image files of themes and plugins would require some form of script to pick up the content (or some htaccess rules)
