Fix · Vercel and deploying

The live site still shows the old version

What you may see

I deployed but my phone or browser shows the old page
A colleague sees the new one and I see the old one

Most likely cause

The browser, a service worker, or a cache in front of the site is still serving the old files.

Check first (about two minutes)

Open the address in a private window or another browser.
Check in Vercel that the newest deployment is the one assigned to your domain.

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

The exact error or what you see

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a patient senior engineer who deploys websites on Vercel every day and explains it to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

THE PROBLEM
The live site still shows the old version

THE EXACT ERROR OR WHAT I SEE

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
The browser, a service worker, or a cache in front of the site is still serving the old files.

DO THESE STEPS, IN THIS ORDER
1. Check that the newest deployment is live on the domain (not only a preview link).
2. Check for a service worker or cache headers that keep old files, and for a proxy or CDN cache in front.
3. Tell me how to clear it: hard refresh, clear site data, and how to purge the CDN cache if there is one.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- A private window shows the new version, and so does my normal browser after clearing the site data.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not disable caching for the whole site.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Check that the newest deployment is live on the domain (not only a preview link).
Check for a service worker or cache headers that keep old files, and for a proxy or CDN cache in front.
Tell me how to clear it: hard refresh, clear site data, and how to purge the CDN cache if there is one.

Do not do this

Do not keep redeploying: it is a cache question.
Do not disable caching for the whole site.
