Most WordPress help online gives you generic answers. This toolkit documents real problems from real production sites — with the exact diagnosis process used to find the root cause, not just the symptom.
Every case study in this repo follows the same structure:
- ❗ Symptom — what the client reported
- 🔍 Diagnosis steps — exactly how I investigated
- 🎯 Root cause — what was actually wrong
- ✅ The fix — what solved it permanently
- 💡 Lesson — what to remember for next time
