Web interface displays as HTML and Pi-hole non-functioning

[syugef8797gf]

Expected Behaviour:

• Web interface (or is it admin console?) at pi.hole displays a graphical user interface
• Pi-hole blocks ads after setting my internet router to use my RaspberryPi's static IP as a DNS

Hardware: Raspberry PI 4 Model B
Operating System: Debian GNU/Linux 12
Tried connecting to pi.hole(/admin) (and static_ip_address/admin) on LibreWolf, Firefox and Safari

Actual Behaviour:

The web interface displays as simply a HTML file on Safari and a white page with text on LibreWolf/Firefox. The console says:

This page is in Quirks Mode. Page layout may be impacted.

Loading failed for the with source “http://192.168.1.150/admin/<?php%20echo%20fileversion('scripts/pi-hole/js/index.js');%20?>”

Additionally, $ pihole status returns that Pi-hole blocking is enabled although advertisements still display on tested websites:

• Google
• Youtube
• Reddit
• etc.

[✗] tcp:*:80 is in use by apache2 (https://docs.pi-hole.net/main/prerequisites/#ports)

Lighttpd is our shipped web server in V5 and earlier. With apache2 sitting on port 80, lighttpd cannot bind to that port.

$ pihole status returns that Pi-hole blocking is enabled although advertisements still display on tested websites:

You have Pi-hole configured for interface eth0, but there is no active interface there:

*** [ DIAGNOSING ]: Setup variables
    PIHOLE_INTERFACE=eth0

*** [ DIAGNOSING ]: Networking
[✗] No IPv4 address(es) found on the eth0 interface.
[✗] No IPv6 address(es) found on the eth0 interface.

*** [ DIAGNOSING ]: Name resolution (IPv4) using a random blocked domain and a known ad-serving domain
[✓] sexyplussizetops.com is 0.0.0.0 on lo (127.0.0.1)
[✓] No IPv4 address available on eth0
[✓] sexyplussizetops.com is 0.0.0.0 on wlan0 (192.168.1.150)
[✓] doubleclick.com is 142.250.180.14 via a remote, public DNS server (8.8.8.8)

You do have an active wlan0 interface, and that is how the Pi is connecting to your network.

Run pihole -r and select the reconfigure option to get Pi-hole onto the wlan0 interface.
