Determination of the cause of a broken page.

If your website's display doesn’t look correct (for example, new content not being updated or certain parts of the page not displaying properly), we recommend following these steps to determine if the issue is related to Fasterize.

1. Using the Fasterize browser extension

a. Install our extension for Chrome or Firefox: This extension allows you to check if an issue observed on a page is caused by Fasterize. You can find more information about it on our blog.

b. Use the extension to diagnose the issue: The extension provides several insights and allows you to view the page without Fasterize optimizations. Simply click on the "See unoptimized pages" button.

c. Analyze the results: If the issue disappears when the optimizations are disabled, you can report it directly to support via the widget available in your console or by following the provided example for reporting issues.

2. Test without Fasterize/CDN (bypass via hosts file)

You can also test the site without Fasterize/CDN by modifying your hosts file locally.

This will allow you to target the original IP of your server directly, to see if the problem is present at the origin.

Steps to follow : 

• Recover the original IP :
  In your Fasterize console, go to the ‘Domains’ application to retrieve your original IP.
• Modify your hosts file  
  On Windows : edit the file C:\Windows\System32\drivers\etc\hosts
  On Mac/Linux: edit the file /etc/hosts
  You must have administrator rights to modify it.
• Add a line like this:
  1.2.3.4 www.votre-site.com
  (Replace 1.2.3.4 with the original IP retrieved from the console)
• Clear your DNS cache
  To ensure that the change is taken into account, clear the DNS cache:
  - On Windows: ipconfig /flushdns
  - On Mac: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
• Reload the page
  You will then be able to navigate directly to your origin, without using Fasterize/CDN (the Fasterize extension will be white).

If the bug is still present after this test, this means that the problem probably comes from the origin (and not from Fasterize).
