If you’re stuck here, you’re not alone. In this guide, you’ll learn exactly how to fix WHM/cPanel Temp URL 404 or Not Supported Error with step-by-step solutions—no server engineering degree required.

A temporary URL is a handy feature in cPanel and WHM environments—it lets you access a website before DNS propagation is complete. For developers, designers, or clients reviewing a new site, temp URLs offer a quick preview without touching the live domain.

But what happens when your temporary URL throws an error like:

“404 Not Found”
“This URL is not supported”
“You don’t have permission to access /~username/”

This is where many users panic. The site is built, the files are uploaded, yet the temp URL just… doesn’t work.

Understanding the Temp URL Structure in cPanel

A typical temp URL in cPanel looks like:

http://your-server-ip/~username/

This is called a mod_userdir URL. It works by mapping the user’s public_html folder to a subdirectory path using Apache’s mod_userdir module.

If your temp URL fails, one of the following is likely true:

  • mod_userdir is disabled on the server
  • The user is restricted from using it
  • Security modules like mod_security or CloudLinux CageFS are blocking access
  • Your .htaccess or script redirects are interfering
