Project description:
"Both of my WordPress sites suddenly started returning “404 Not Found” for every post and article. Home pages still load, so the problem seems to sit somewhere between permalinks, server rules, or a corrupted .htaccess/Nginx configuration—but I’m not certain. I need someone who can jump in right away, look through the server logs, WordPress core files, database, and any plugin or theme hooks that might be interfering, then put everything back the way it should be.

What I expect from you:
• Pinpoint the exact cause of the 404s on both sites.
• Apply a clean, permanent fix so every existing URL works again.
• Verify that new posts publish without issues.
• Hand me a brief report outlining the root cause and the steps you took to resolve it (for future reference).

You will have full admin, cPanel/SSH and phpMyAdmin access as soon as we start. Please be ready to begin immediately and keep communication open while you work; this outage is business-critical." (client-provided description)
