WordPress documentation is fragmented. The official docs cover the "how" but rarely the "why" or the "what to do when it doesn't work". Third-party tutorials are often outdated, skip important context, or are written to rank for keywords rather than to actually solve the problem.
The guides here are written for people who need things to actually work: step-by-step instructions with the real context about what each step does, why it matters, and what to check if something goes wrong. Most include the specific error messages you'll encounter and how to diagnose them.
The fix guides cover the WordPress errors that send people to search in a panic: the white screen of death, 504 gateway timeouts, database connection errors, memory exhausted notices, and mixed content warnings after migrating to HTTPS. Each guide explains what's actually causing the error, not just the one command that sometimes fixes it.
The setup and configuration guides cover: WordPress multisite (when it makes sense and how to configure it correctly), WordPress child themes (why you need one and how to structure it), local WordPress development with Docker or LocalWP, and WordPress migration between hosts without breaking anything. These are the tasks that come up constantly in agency work — having a reliable reference for each saves the research time every time.
