We recently launched a client's new website that is a WP multisite install. Each metro area location has its own site. Before it was just a single, simple html based site. I am attempting to set up 301 redirects for all the old site files ending in .html to 301 to their new locations on the main domain. But whenever I try and set up a 301 from say: /paper.html to /products/paper-products/, the site actually redirects it back to the homepage.
