nginx v1.10.2 Passenger 403 : Multiple virtual hosts on my workstation, just stopped working.  Upon an update of `nginx` to v1.10.2 and a new `Passenger` `locations.ini` file pointer in the `nginx.conf` file, I'm getting `403 Forbidden` permissions errors on all of these vhosts.  No clue what to look at.

    passenger_root /usr/local/opt/passenger/libexec/src/ruby_supportlib/phusion_passenger/locations.ini;
    passenger_ruby /usr/bin/ruby;

But, `which ruby`:

    /Users/rich/.rbenv/shims/ruby

So I changed that directive to the one above.  Restart `nginx`, and still the same.  The error reported:

    2017/10/23 19:51:36 [error] 10863#0: *61 directory index of "/Library/WebServer/Documents/HQ/public/" is forbidden, client: 127.0.0.1, server: hq.local, request: "GET / HTTP/1.1", host: "hq.local"

Permissions haven't changed ever.  Not to mention they are relaxed (only seen by me):

    drwxrwxrwx  20 rich  admin   680B Jun 17 01:52 HQ
    cd HQ:
    drwxr-xr-x   8 rich  admin   272B Jul 12 17:32 public

Odd stuff.  Any ideas appreciated how to get all this serving again properly.  It seems permissions were completely thrown off, and I'm not sure if it was the `nginx` update or not.  Cheers
