A change log is a simple running record of what changed on your website and when — invaluable the moment something unexpectedly breaks.
Why It Matters
When a site suddenly behaves oddly, the first useful question is "what changed recently?" — a change log answers that instantly instead of requiring guesswork.
What to Log
Plugin and theme updates, code changes, DNS modifications, and any configuration change worth remembering all belong in the log.
Keep It Simple
A basic spreadsheet or shared document with date, change, and who made it is more than sufficient — the goal is a habit that actually gets maintained, not a perfect system.
