Looks like you're missing the CSS files; Most often, this is because the phabricator.base-uri configuration value is not configured correctly.
navigate to /config/ to configure it to the correct value.

The CSS doesn't look to be loading. Please check permission and webserver configs.

I can't test this until I go home, since this is on my home server, and I don't think the suggested settings that the install docs work unless I get an externally registered domain name. I test on my Windows 10 box, by adding my home server's IP, pointing it to http://phabricator.thrall.com

However, I have added the nginx.conf file here, in hopes that you might see something incorrect, along with some info below:

• I had already set phabricator.base-uri to http://phabricator.thrall.com, but I just noticed that there are two sections, and one has "null":

thrall:/srv/www/htdocs/phabricator/phabricator/bin # ./config get phabricator.base-uri
{
  "config": [
    {
      "key": "phabricator.base-uri",
      "source": "local",
      "value": "http:\/\/phabricator.thrall.com\/",
      "status": "set",
      "errorInfo": null
    },
    {
      "key": "phabricator.base-uri",
      "source": "database",
      "value": null,
      "status": "unset",
      "errorInfo": null
    }
  ]
}

• Regarding permissions, all of the phabricator-related files/folders are owned by wwwrun:www, the default web server user:group on my server.
• nginx.conf4 KBDownload

I hope this sheds some light.

Thanks

You don't need an external domain. I use 'http://dev.macbook.local/' and update my local dns per computer accordingly. You should have more information as to what's wrong if your web server's error log.

I know this is closed, but I wanted to add how I eventually solved it. I paid more attention to my error logs (nginx), and noticed I had a permission issue. I have "wwwrun" as the nginx user, but I forgot to check /var/lib/nginx ownership; it was owned by nginx.

With the correct permissions, I have beautiful, sexy css! :D
