I have just published a new article on my custom-built website, but visiting the URL instantly returns a 404 page. Nothing in the site’s structure, routing, or file names has changed recently, so the problem is isolated to this single post rather than a global configuration issue. I need someone to trace why the freshly generated link is not being recognised by the server, correct whatever is blocking or mis-routing the request, and make the post load normally. The site runs on a bespoke PHP stack (no CMS), so you may need to review .htaccess rules, routing scripts, and any slug-generation logic. When the job is done I expect: • The post reachable at its intended URL without redirect loops or errors • A brief note (a few lines) explaining the root cause and the fix so I can avoid repeats in future Please let me know how soon you can start and roughly how long you’ll need once you have server access.
