Botched Apache2 on Ubuntu development machine. How to start fresh?

I had my Apache2 running good on my development machine.

I changed some site configurations and started running the noip.com's client, even though this is a production machine, to see if I could access it from the world wide web.

I tried to install it in terminal and came across the following error

brian@brian-XPS-13:~$ sudo service apache2 start
[sudo] password for brian: 
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.

If this question isn't answered today I may not be able to get on the computer for a few days. I will come back to it Monday at the latest.
