Fix Critical WordPress Errors

I’m dealing with a sudden wave of errors across several WordPress installs—white screens, “Page Not Found” notices, and pages that refuse to load at all. The problems affect both the public-facing site and the admin dashboard, so visitors and editors are equally locked out.

No themes or plugins were updated and no code edits were made right before this happened, so I’m expecting you to dive straight into log files, plugin conflicts, database integrity, and PHP version compatibility to uncover what went wrong. Everything sits on a standard shared-hosting stack (cPanel, Apache, MySQL, PHP), so please be comfortable working within those limits—SSH, phpMyAdmin, error_log, and any quick .htaccess tweaks may all be needed.

I need you ready to start the moment we agree, isolate the root cause fast, and apply a clean fix that restores normal page loads without breaking future updates. Once complete, a brief summary of what was wrong and what you changed will be enough for me to keep on file.
