About this gig

Is your PHP, WordPress, JavaScript or MySQL site broken? I fix it and tell you exactly what went wrong. I have 25 years of experience building and running PHP and MySQL sites that stay online under heavy traffic. What I fix: PHP errors, warnings and white screens; WordPress theme, plugin and login problems; JavaScript and jQuery that stop working; layout that breaks on phones; slow or failing MySQL queries. How it works: send me the error message or a screenshot and access to a test copy of the site. I reproduce the problem, fix it, test it, and explain the cause in plain English. Please message me before ordering so I can confirm the fix fits one of the packages.
