What could be causing the issue with the broken URL in Webflow that includes "www.www." and what steps can be taken to fix it?

A "www.www." URL prefix issue in Webflow typically happens due to incorrect domain configuration or DNS settings. This can lead to broken links, redirect loops, or a non-loading site.

1. Check Domain Settings in Webflow

• Go to Project Settings → Hosting tab in the Webflow Designer.
• In the Custom Domains section, make sure your primary domain is correctly set as either www.yourdomain.com or yourdomain.com, but not both with "www.".
• If you see www.www.yourdomain.com listed, delete it — that's not a valid domain.

2. Set a Default Domain

• In the Hosting tab, ensure exactly one domain is selected as the default (indicated by the green checkmark).
• Webflow recommends setting the www version (e.g., www.yourdomain.com) as the default domain.
• Click the "Make default" button next to the correct domain if necessary.

3. Verify Redirect Settings

• Webflow automatically creates 301 redirects from non-www to www (or vice versa) depending on your default domain setting.
• If you manually added redirects under Project Settings → Hosting → 301 Redirects, make sure they don’t include a misconfigured value like "www.www.".

4. Check DNS Settings at Your Registrar

• Log into your domain registrar (e.g., GoDaddy, Namecheap) and locate your DNS records.
• Ensure the www CNAME points to proxy-ssl.webflow.com.
• Do not create a CNAME or A record with a host like www.www — this is invalid.

5. Clear Browser Cache or Test in Incognito

• Sometimes a cached redirect or DNS entry can make things appear worse.
• Test the domain in Incognito mode or clear DNS cache if needed.

Summary

The "www.www." URL issue is almost always caused by incorrect domain or DNS configuration. To fix it, ensure your Webflow project has the correct domains listed (without duplicates), set a proper default domain (usually www), and check that DNS settings at your registrar don’t include an invalid “www.www” entry.
