I’ve managed to make a fatal and parse error…

I don’t know how I’ve done it, but I’ve managed to make a fatal error with my WP comments, and a parse error with my vars file. I have recently edited both of those files, (and am sure I must have done something.) but I don’t know what I did? I can’t find a way to download the file either, since it’s version 1.2.1

I’ll start by posting the vars file:
<?php
