I've installed wpmu successfully using diretory structure for new blog. All features seems to be working so far but I noticed one thing that can cause problem.
For example if I enter the URL: http://www.example.com/blog1/2005/10/20/non-existent/ it returns 404 but
http://www.example.com/blog1/non-existent1/ returns the homepage instead of 404. If there is a page with the name non-existent1 it displays correctly though.
How can I change it so that it returns 404 instead of the homepage? I examined the header and it indeed returns 200.
