Live view and browser preview stopped working after switching from HTML to PHP

Report · Sep 24, 2025

Hi everyone,

a) My live view stopped working after I gradually changed my website from plain HTML to PHP. The same page works fine as xxx.html, but with xxx.php I get the following error:

“An unknown error occurred while searching for dynamically related files.”

b) The browser preview no longer works either, and the QR code for previewing on mobile is also not showing up anymore.

Does anyone know what could be causing this or how to fix it?

Thanks in advance for any help!

PHP is a pretext processor script. Do you have a testing server running? If no, then that could be causing your issue with live view as PHP pages need to be processed by a server so it gets turned into HTML to be displayed in the browser. If the server is not running, DW will be unable to find the dynamically related files and show content on the page such as QR codes, and browser previews will fail as well as it will look for the testing server that either does not exist or is offline.

What are you using for your testing server? Is it a remote server, and if so is that configured?

Or are you running a local server (ie: MAMP/WAMP) and is it running while you are building in DW?
