My WordPress site is completely down and visitors only see an error page. I do not have a recent backup to roll back to, so I need someone who can get the existing installation running again without data loss. I got the following message: "This page isn’t working wakoz.com is currently unable to handle this request. HTTP ERROR 500" Key requirements • Diagnose why WordPress is inaccessible and bring the front-end and admin dashboard back online. • Preserve all current content, themes, and plugins while fixing the issue—there is no backup to fall back on. • Provide a short summary of what was wrong and the steps you took so I can avoid another outage. cPanel and FTP credentials are ready; DNS and hosting remain unchanged. Please restore the site as soon as possible and confirm it loads normally on both desktop and mobile once you’re done.
