About this gig

Is your WordPress site showing a white screen, a fatal error, or just not doing what it should? I'll find the real cause and fix it safely.


WHAT I FIX:

Fatal errors and the "white screen of death"

Sites broken after a plugin, theme, or PHP version update

Contact forms not sending, pages not loading, features misbehaving

Custom PHP code that stopped working


HOW I WORK:

Backup first I never edit a live site without a safety copy

I fix the actual cause, not just hide the error message

You get a plain-English summary of what was wrong and what I changed


40 years of professional software experience. PHP and MySQL have been part of my daily work for years.


Please message me BEFORE ordering send your site link and a description or screenshot of the problem, and I'll confirm the price and delivery time. Diagnosis is free.
