I'm having trouble deploying overall, but after tweaking various configs all day, deploying seems to be successful.

But when I go to my site, I just see the nginx page.

I try to restart unicorn and it always fails:

$cap production deploy:restart --trace
** Invoke production (first_time)

Any ideas?
