Why does my computer show an old version of a web site

/ Blog / By
The most common reason your computer shows an old version of a website is that your browser is displaying a cached copy of the site to load it faster.
Browsers save website resources like images, HTML, and CSS files locally so they don’t have to download everything again on a repeat visit. 
In addition to your browser, your internet service provider (ISP) or a content delivery network (CDN) can also store cached versions of websites. 
Solutions for your computer
To fix the issue on your end, follow these steps:
1. Perform a hard refresh
A hard refresh forces your browser to bypass its cache and download the latest version of the website.
  • On Windows: Press Ctrl + Shift + R or Ctrl + F5.
  • On Mac: Press Cmd + Shift + R.

2. Clear your browser’s cache and cookies

If a hard refresh doesn’t work, clear your browser’s entire cache for a more thorough reset.
  • Google Chrome: Open the menu (three dots) > More tools > Clear browsing data. Set the time range to All time and make sure Cached images and files is checked.
  • Mozilla Firefox: Open the menu (three lines) > Settings > Privacy & Security. In the Cookies and Site Data section, click Clear Data.
  • Microsoft Edge: Open the menu (three dots) > Settings > Privacy, search, and services. Under “Clear browsing data,” click Choose what to clear. 

Clear Browser Cache

  • Google Chrome:
    • Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac).
    • Select “Cached images and files” and clear data for “All time.”
    • Reload your site with Ctrl+F5 for a hard refresh.
  • Firefox:
    • Press Ctrl+Shift+Delete, select “Cache,” and clear.
    • Reload with Ctrl+F5.

3. Use an incognito or private window

An incognito or private browsing window won’t use your browser’s existing cache, allowing you to test if the problem is specific to your browser’s saved data. 
4. Flush your DNS cache
Your computer also has its own cache for DNS (Domain Name System) information, which stores the IP address for websites you’ve visited.
  • On Windows: Open the Command Prompt, type ipconfig /flushdns, and press Enter.
  • On Mac: Open the Terminal and type sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder and press Enter.

Reasons for server-side caching

If the issue persists after following the steps above, the old version of the site may be cached on the server side by the website owner, their hosting provider, or their CDN. In this case, you will have to wait for them to resolve the issue. 
For website developers
If you are the website owner, here are some common causes:
  • CDN cache: If you use a Content Delivery Network like Cloudflare, you may need to log into its dashboard and manually purge the cache.
  • Server-side cache: Your hosting provider or caching plugins (e.g., in WordPress) may be serving an old version of the site.
  • Stale DNS records: If you recently migrated the website, the DNS changes may not have fully propagated across the internet. This process can take up to 48 hours.
