"502 Bad Gateway nginx/1.4.6 (Ubuntu)" error after upgrrading ghost from 0.7.9 to 0.11.1

Posted on March 26, 2017

I just upgrade ghost from 0.7.9 to 0.11.1 by following this guide on ghost.org.. After the upgrade which completed without errors I get “502 Bad Gateway nginx/1.4.6 (Ubuntu)” when I try to visit the site. When I revert to my backup everything works fine. And when I say “revert to my backup” I don’t mean restoring the whole server I just mean “cp -R ./ghost-backup ./ghost”. A reboot was not required after reverting back to the backup either. Something is failing with the upgrade but I have no idea what.

My theme is Casper 1.2.8.

This is what appeared in the error log for nginx.

2017/03/26 05:32:23 [error] 1062#0: *21 connect() failed (111: Connection refused) while connecting to upstream, client: [client IP], server: site.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:2368/", host: "www.site.com"

It seems that the problem was the theme. Before doing the log test you suggested I finally upgraded the theme. I hesitated because the documentation made it sound optional and I wasn’t sure if I’d modified the theme or not.

So I think we can conclude that Casper 1.2.8 does not work on Ghost 0.11.1. The documentation could be clearer, they make it sound like upgrading the theme is optional.
