When I run lein ring server from within the app directory I get the following NPE

I think this was because I had another process running on 3000. Once I killed it I get

Shut down my server and attempted to restart with the hope that nothing would be running on 3000 with the following results

There is something not quite right here that we need to iron out

Fixed it. Looks like we needed an explicit "else" clause in the check for a language code in the domain.
