The approach that works.
THE FIRST FOUR QUESTIONS
What exactly happens? When did it start? What changed? Does it affect everyone, or only you?
WHY THOSE
They eliminate most possibilities immediately.
THE "WHAT CHANGED" QUESTION
Almost every problem follows a change: an update, a plugin, a setting, a DNS change, an expiry.
Establish what changed and you have usually found it.
THE "EVERYONE OR ONLY YOU" QUESTION
Check from another network and another device.
A problem only you see is local: caching, DNS, or your network.
WHAT TO DO NEXT
Change one thing at a time Test after each Record what you tried
WHY ONE AT A TIME
Changing several things means you never learn which fixed it, and you may cause new problems.
WHAT TO DO BEFORE CHANGING ANYTHING
Back up.
WHAT TO AVOID
Following instructions you do not understand Applying fixes for a different problem Panicking and changing many settings
WHEN TO ASK FOR HELP
When you have established the facts and cannot proceed.
Open a ticket with what you found.
