You are using Apache, not lighttpd:

*** [ DIAGNOSING ]: Dashboard headers
[✗] Web interface X-Header: X-Header does not match or could not be retrieved.
HTTP/1.1 200 OK
Date: Sun, 12 Mar 2023 16:36:02 GMT
Server: Apache/2.4.54 (Debian)

This shows Apache is not configured to handle PHP files.

If you look in the header of the file you changed, you will see this:

cat /etc/lighttpd/lighttpd.conf | grep '#'

What is the complete URL you are using in Firefox to access the web admin GUI?

~Update~

  1. I missed the prerequisites about Apache Prerequisites - Pi-hole documentation
    I ran sudo systemctl disable apache2 && sudo systemctl stop apache2

  2. I didn't see the header in nano in putty. Is there a better view to use?
    since disabling apache I reverted back to port 80

  3. I have a friend using ubuntu who has no issues their debug file shows PHP 8.1.7
    for some reason, Debian ran on PHP 7.4.1
    I updated to 8.2.3 and it resolved the issue I was facing

  1. Disabling Apache should fix the issues.

  2. If you are using only lighttpd, you don't need to set a different port (as you already noticed), but if you want to change the port for whatever reason, the best way to do it is creating a new config file in /etc/lighttpd/conf-enabled/ directory with the new port.

    Example: /etc/lighttpd/conf-enabled/15-pihole-admin-port.conf:

    server.port := 8888

  3. After disabling Apache, PHP pages will be handled by lighttpd web server. Pi-hole would work even with PHP 7.0. The issue you had before was not related to PHP version. The problem was Apache was not configured to use PHP.
