Finding Default RACHEL-Pi Files

A user e-mailed with:

Please can you spare a few moments to help me.

I purchased a Rachel Pi from you which I use in remote northern Vanuatu in a school.

I was trying to also make the pi into a webdav server.

It was all based on:
http://www.head4space.com/pidav-webdav-raspberry-pi-tutorial-part-two/

BUT in the process I made a disasterous mistake, and deleted the following file:

sudo rm /etc/apache2/sites-available/default

…which has made Rachel Pi no longer functional.

Please can you help me to get a copy of this file so I can replace it?

You can find default copies of the RACHEL-Pi files on our GitHub: https://github.com/rachelproject/rachelpiOS/tree/master/files

This particular file is here: https://github.com/rachelproject/rachelpiOS/blob/master/files/default
