Urgent WordPress Issue Fix

My WordPress site has hit a critical snag and I need it back online right away. The exact point of failure is still unclear—front-end pages are throwing a fatal error and the admin dashboard is locked behind a white screen. No troubleshooting steps have been taken yet, so you will be starting with a clean slate to isolate the root cause.

The task revolves around:

• Rapid diagnostics of core files, active theme, and plugins through error logs, WP-DEBUG, or direct inspection over FTP / cPanel.
• Immediate remediation—whether that means repairing corrupt core files, rolling back a faulty update, or refactoring a misbehaving function in functions.php.
• Verifying the database with phpMyAdmin to ensure no missing tables or mis-configured options are contributing to the crash.
• Restoring full site functionality and confirming both public pages and wp-admin load quickly without throwing PHP or JavaScript errors.

Acceptance criteria
1. Site loads on the front end with no visible errors.
2. wp-admin is accessible and stable.
3. A brief summary report outlines the root cause, the fixes applied, and any preventive recommendations.

SSH, SFTP, and WordPress admin credentials will be handed over immediately after project start so you can begin the fix on the spot. I’m available in real time to provide any additional hosting access or DNS adjustments you might need.
