THE REAL PROBLEM (Not Caching!):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Nginx was NOT routing pages to the backend!

❌ When you accessed: http://localhost/home
   ↓
   Nginx tried to find: /media/pts/Website/SkyArtShop/website/public/home
   ↓
   File doesn't exist → 404 Not Found

✅ What SHOULD happen:
   http://localhost/home
   ↓
   Nginx proxies to: http://localhost:5000/home
   ↓
   Backend serves the page with ALL your changes


WHAT WAS CONFIGURED:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Nginx was ONLY proxying these routes to backend:
  ✓ / (root)
  ✓ /api/*
  ✓ /app/*
  ✓ /health

Nginx was NOT proxying these (returned 404):
  ✗ /home
  ✗ /shop
  ✗ /product
  ✗ /about
  ✗ /contact
  ✗ /blog
  ✗ /portfolio
  ✗ /faq
  ✗ /privacy
  ✗ /returns
  ✗ /shipping-info


THE FIX APPLIED:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Added to /etc/nginx/sites-available/skyartshop:

    location ~ ^/(home|shop|product|about|contact|blog|portfolio|faq|privacy|returns|shipping-info)$ {
        proxy_pass http://localhost:5000;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

This was added to BOTH HTTP and HTTPS server blocks.


OTHER FIXES THAT WERE ACTUALLY NEEDED:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. ✅ Nginx /assets/ path: Fixed from /var/www/skyartshop/ → /media/pts/Website/SkyArtShop/website/public/
2. ✅ Nginx /uploads/ path: Same fix
3. ✅ Cache-busting versions: Updated to v=1768448784
4. ✅ Sticky navbar CSS: Added .sticky-banner-wrapper
5. ✅ PM2 backend restart: Cleared memory cache


VERIFICATION:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ http://localhost/home → Returns HTML (no more 404)
✅ http://localhost/shop → Returns HTML
✅ navbar.css?v=1768448784 → Loading with new version
✅ .sticky-banner-wrapper CSS → Present in file
✅ Backend serving from: /media/pts/Website/SkyArtShop/website/


THERE IS ONLY ONE WEBSITE FOLDER:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Confirmed - No duplicate folders:
  ✓ ONE source: /media/pts/Website/SkyArtShop/website/public/
  ✗ /var/www/skyartshop - DOES NOT EXIST (was a typo in old config)
  ✗ No other copies found


WHY THIS HAPPENED:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The nginx configuration was incomplete. It was set up to proxy API calls
and the root path, but someone forgot to add the frontend page routes.

This meant:
- Backend had all your changes ✓
- Files had all your changes ✓
- But nginx wasn't letting requests reach the backend ✗


WHAT YOU NEED TO DO NOW:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Open your website in browser
2. Hard refresh: Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac)
3. All changes should now be visible:
   - Sticky navbar
   - Cart/wishlist working
   - All refactoring changes
   - Security headers
   - Standardized layouts


THE GOOD NEWS:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ There is only ONE website folder
✅ All your changes ARE in the files
✅ The backend IS serving correctly
✅ NOW nginx is routing correctly too

This problem is PERMANENTLY FIXED. Future changes will reflect immediately
after PM2 restart (if needed) and browser hard refresh.

Apologies for the frustration - this nginx routing issue should have been
caught in the initial investigation.
