XAMPP apache will not start

Question

I had to reinstall my max with El capitan, and I had XAMPP working with mysql and apache able to start servers. Now my apache server isn't able to start so I can't get to phpmyadmin to do some schoolwork.

I've looked around and saw that it could be a port 80 or 81 issue, so I checked and saw that no applications were currently using the port, either way I still got a no go.

I tried through terminal to see an error message,

Starting XAMPP for Mac OS X 5.6.30-0...
XAMPP: Starting Apache...fail.
XAMPP:  Starting diagnose... 
XAMPP:  Sorry, I've no idea what's going wrong. 
XAMPP:  Please contact our forum http://www.apachefriends.org/f/ 
Last 10 lines of "/Applications/XAMPP/xamppfiles/logs/error_log":

Thought I would post my problem here while I browse around for more possible solutions.

Update your system and install net-tools

On ubuntu, sudo apt update then sudo apt install net-tools -y restart your server
