About the Book
A step-by-step guide for people who run their own WordPress site — for a shop, a school, an office, or a small business — and want to fix common problems themselves. (8 chapters, information as of October 2026.)
Each chapter explains where to look, how to judge what you see, and how to roll back if something doesn't work:
Chapter 1. 10 Checks to Do Before Updating PHP
Chapter 2. How to Fix "There Has Been a Critical Error on This Website"
Chapter 3. How to Fix a Blank White Screen
Chapter 4. How to Fix "Error Establishing a Database Connection"
Chapter 5. When Contact Form Emails Don't Arrive
Chapter 6. Preparing for a Server Move Yourself
Chapter 7. What to Do When You See a "Vulnerability" or "Security Update" Notice
Chapter 8. What to Do First When Your Site May Have Been Hacked
Every chapter ends with "signs that fixing it yourself is too hard", so you know when to stop and ask for help. These steps won't fix every site; sites with a lot of custom code may need a professional.
Written with the help of AI tools and reviewed by the author.

About the Author
MICHITERU MODA
WordPress maintenance engineer based in Japan. Since 2016, I've handled 500+ PHP updates and site troubles.
I help site owners with safe PHP version updates, "There has been a critical error on this website", white screens, admin login problems, broken layouts after plugin or theme updates, server migrations, and SSL setup.
How I work: I take a full backup before touching anything, diagnose the cause with my own checking tool, fix only what is needed, and explain what happened in plain language. My books follow the same approach, so you can do it yourself.
