Fix WordPress PHP Error (Windows)

Job ID: 39816161

Budget: $10 – $30 AUD

My WordPress site is hosted on a Windows Server and has suddenly started throwing PHP-level errors on the front end. Every public page now shows the error instead of loading normally, even though the database and server themselves appear to be running fine. I need someone who can:

• diagnose the exact PHP issue (theme, plugin, or core conflict)
• patch or re-configure the installation so pages render correctly again
• confirm the admin dashboard opens without warnings
• give me a short summary of what went wrong and any preventive steps I should take

You’ll be working directly on a live Windows environment, so familiarity with IIS, PHP error logs, wp-config settings, and common WordPress hardening practices is essential. Please highlight relevant experience you’ve had fixing similar PHP errors on WordPress—especially when the site is running under Windows Server. A quick, clean fix that avoids downtime is my priority.
