I am setting up a WordPress multisite site using subfolders like this:
Site One: example.com/site_one
Site Two: example.com/site_two
Site Three: example.com/site_one/site_three
Site One and Site Two works fine, Site Three looks fine when I look at the database tables, but visiting example.com/site_one/site_three results in a 404 error, from my testing I can work out that all example.com/site_one/* addresses are being interpreted as parts of example.com/site_one and that this takes priority over sensing which address belongs to a subsite. How do I make WordPress recognize example.com/site_one/site_three as a subsite and not a Page belonging to example.com/site_one?
