@julian Yeah, I was start NodeBB in root:

@julian

I was following this guide to install my Nginx:
https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-14-04-lts

But I didn't use a regular, non-root user to install it (I installed it using root user), maybe this is the problem ?

@julian

@julian I was created this file as root user...

@julian Yes, I have restart it, using sudo service nginx restart

@julian It has:

When I configured Nginx on my Linode server, I still unable to visit my website without a port number:

But with a port number, it can be visited:

My server OS is Ubuntu 14.04 LTS, Nginx version is 1.4.6:

And in /etc/nginx/sites-available and /etc/nginx/sites-enabled, I have my configuration file named "huoshaolin", the contents are:

server {
    listen 80;

    server_name huoshaolin.com www.huoshaolin.com;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:4567/;
        proxy_redirect off;

        # Socket.IO Support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

I just modified it base on the doc: https://docs.nodebb.org/en/latest/configuring/proxies/nginx.html

When I ran nginx -t , it looks fine (I think):

And the /etc/nginx/nginx.conf also changed:

So what's the problem about this 502 Bad Gateway ?

@julian Thanks, now it's no problem : )

When I install NodeBB on my local Windows 8.1, I also have this problem :

I was following this guide : https://docs.nodebb.org/en/latest/installing/os/windows8.html

@a_5mith Me too ...

@psychobunny Thanks !

@helltux Thanks for your link : )

In the theme "nodebb-theme-vanilla", there have a "bootstrap-rtl" folder, what does it do? And what "rtl" means?

@a_5mith Thanks for your advice : )
