Hello,
Updated today to pi-hole 6 and the webserver broke.
Looks like the "index file" is missing and i just see the file listing:
Details about my system:
System is Ubuntu LTS with apache running and reserving the webservice ports.
'What I have changed since installing Pi-hole:*
Checked the toml and tried to fiddle with ports, but kinda no idea what i'm doing
**EDIT: ** debug log: https://tricorder.pi-hole.net/EdpPk2rI/
Any idea what whent wrong and how to fix it?

you might want to generate a token and posted, so Mod and Dev and diagnose your issue
Okay, thank you for your help. I´ll try to figure out how to do that.
Debug log: https://tricorder.pi-hole.net/EdpPk2rI/
[✗] tcp:*:80 is in use by apache2 (https://docs.pi-hole.net/main/prerequisites/#ports)
[✗] tcp:*:443 is in use by apache2 (https://docs.pi-hole.net/main/prerequisites/#ports)
There's your issue - port 80 and 443 are already bound by apache - if you're not using this for anything else, then you can probably disable it, or you can update the pi-hole config to utilise different port numbers by adjusting the config file as you already have done (but with, for example, 8080 instead of 80)
Okay changed the port to 8080 (maybe)
So the service should be available from http://ip:8080/admin (/pi in my case)?
New debug log here: https://tricorder.pi-hole.net/PWBdRW2K/

Looks about right. Though you're still missing that additional colon between [::] and 8080 per @smurf's suggestion.
Try this:
port = "8080o,[::]:8080o,443so,[::]:443so"
Dang, stepped on the same mine 2 times.. 
. I must confess i have a little issue with dyslexia.
Here's the latest change:
Looks promising
Site loads now, but with 404 error
and a new log

Hang on. Why are you navigating to /pi/ ?
It should be at /admin/!
In my paranoia i didn't want the administration page exposed to "easily recognizable" folder like admin (and now i told the folder to whole world 
)
So i changed the path into the toml and webserver
But i guess i can revert to default admin folder since the port 8080 is not exposed to wan port and is reachable only in lan.

Reverted back to /admin and it works with http://ip:8080/admin/
What a strange endeavour this update was .
Anyways BIG thank you for @smurf & @promofaux for your kindness & help
Yours
