Pi OS -- web page incomplete.

Pi OS all up to date (was raspbian).
nagios 4.4.6 all compiled and installed and seemingly groovy.
The plugins compiled and installed and seemingly groovy. But my problem
occurs when trying to test the website after installing nagios.

the instructions say:

You will be prompted for a username and password. The username is nagiosadmin (you created it in a previous step) and the password is what you provided earlier.

Once you have logged in you are presented with the Nagios interface. Congratulations you have installed Nagios Core.

Ah, no. I go to this place, I **am** prompted for a user/pass, which I
give it, and I get to a page that says:

http://cyril.jgscrater.com/nagios/

Not Found

The requested URL was not found on this server.
Apache/2.4.38 (Raspbian) Server at cyril.jgscrater.com Port 80

in the left hand column I get stuff like this:

/tac.cgi" target="">Tactical Overview
Map /statusmap.cgi?host=all" target="">(Legacy)
/status.cgi?hostgroup=all&style=hostdetail"

I've never turned on selinux or iptables and so on.
So I'm convinced this is not a permissions problem.
Anyway, I get the page, it just doesn't look right.

From /var/log/apache2:
**nothing** in the error log from today.
the access.log

Only one line above has a 404 return code.

So the LHS is wrong, and the RHS is blank. Huh? Wha?
my nagios.cfg file (and similar) are totally stock.
