KW Members Fortress turns a standalone WordPress site into a private, members-only space. Visitors who aren’t logged in can’t reach anything except the login screen and the legal pages you choose to publish — not your pages, posts, archives, search, feeds, REST API, sitemaps, XML-RPC, and crucially not your uploaded files either.
Most “force login” plugins only gate the pages WordPress renders. They leave every file in /wp-content/uploads/ reachable by anyone who has (or guesses) the URL — PDFs, images, documents. KW Members Fortress routes those file requests through WordPress and serves them only to logged-in members, then continuously self-tests that the seal is holding.
/wp-content/uploads/… are served only to members (Apache/LiteSpeed handled automatically; nginx shows you the one snippet to paste).…/wp-content/uploads/kw-members-fortress/ — never in the plugin folder.
