This looks OK.

If you don't see anything then Plack is not enabled.

This is not correct - it seems it was not possible to enable Plack.
You never mentioned your operating system or the Koha version you
installed. Did you follow these instructions when installing Koha?
* https://wiki.koha-community.org/wiki/Koha_on_Debian
Today David Liddle wrote in his e-mail to you:
"You might want to also check the existence and content of the following
files:
/etc/koha/apache-shared-intranet-plack.conf
/etc/koha/apache-shared-opac-plack.conf
as well as their references within the file of this instance-based name:
/etc/apache2/sites-enabled/library.conf
If you somehow wound up with an Apache configuration that isn't being
managed by the Koha tools, then it could be interfering."
Hope this helps.
Best wishes: Michael
