Reverse proxy using apache2 (httpd) does not allow creation of pages

[o-k-a-y]

I'm trying to run wikijs on wiki.domain.com but am encountering errors when running and attempting to create/update my home page.

When I run the page, it seems incomplete to begin with (broken images, broken links).
If i go to wiki.domain.com:3000/create/home, I get as html

DiscardSave Document
<!-- TITLE: Home -->
<!-- SUBTITLE: A quick summary of Home -->

# Header
Powered by Wiki.js.

    Home
    Return to top

The DiscardSave I'm assuming are supposed to be two separate buttons but it's just one html string I can't click or do anything with.

In my config.yml for wikijs I have

host: 'localhost'
port: 3000

My apache2 conf for subdomain

<VirtualHost *:80>

        ServerName wiki.craftmine.org
        ServerAlias www.wiki.domain.com

        ServerAdmin webmaster@localhost
