As of version 0.4.1 the standard WordPress redirect no longer works. Disabling the WordPress SEO plugin fixes the problem. Also rolling back to the previous version fixes it so assume bug was introduced in latest version?
Problem: http://mywebsite.com/<page-name> should redirect to http://mywebsite.com/full/path/to/page/<page-name> (this is a standard WordPress feature). After the plugin upgrade, URLs of this type (http://mywebsite.com/<page-name>) now return a 404.
