[Mailman-Developers] 500 internal server error when accessing /postorius/

[fsantiago at garbage-juice.com]

Hello,

I've installed mailman3, postorius, and hyperkitty from the repo:

http://repos.fedorapeople.org/repos/abompard/hyperkitty/stable/fedora-$releasever/$basearch/

on centos 7. i have python 2.7 & 3.4 installed as well.

mailman3 server starts fine (seemingly).

But in apache i'm receiving the following error logs:
