Problem with Apache2 after upgrade from Ubuntu14.04 to 16.04

[Purvez <purvez@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi

Newbie to the forum here so I hope I'm doing this right.  If not please would someone guide me.  Thx in advance.

As the subject line says Apache2 is not working at all / satisfactorily since the Ubuntu upgrade.  The details follow:

===========================

Here is my full post on askubuntu:

Currently the biggest help I could get would be if someone would decipher what the following output means when I do :

systemctl status apache2.service

output:
===============

Code:

purvez@127:~$ systemctl status apache2.service

purvez@127:~$

The MAIN question is : Is Apache started and functioning or is it inactive (dead)?

The last line of the output suggests that it is working but the 5th / 6th line from the top suggests the opposite.

The errorlog is blank and the accesslog is blank as well since the day of the upgrade.
===========================
Thanks in advance
