Only some routes work on Node express

I've been developing a website for a while now locally. Using Ubuntu, nodejs and express. I recently moved it to my VPS on Dreamhost and it has some strange behavior. Everything worked fine on my localhost but on the VPS only some routes work. By this I mean if I go to mydomain.com then I get the website. Then if I go to mydomain.com/panel it loads, however, it is supposed to check for a user session but doesn't, it just sends them to the panel. Then if I try to go to mydomain.com/contact or any other route on my website, it just won't load. I get a 500 error.

This is my panel route, which is found in routes/panel.js

router.get('/', function(req, res, next) {
  var sess = req.session;
  if(sess.user) res.status(200).sendFile(path.resolve(__dirname + '/../public/panel.html'));
  else res.status(200).sendFile(path.resolve(__dirname + '/../public/admin.html'));
});

This is my contact route, which is found in routes/contact.js

router.get('/', function(req, res) {
  res.send("Hello");
});

In app.js I add both of these routes like this,

app.use('/contact', contact);
app.use('/panel', panel);

This all works on my localhost. All of the correct modules are present. For some reason it is not working on the Dreamhost VPS.

Any ideas?
