502 Bad Gateway after Ghost upgrade
my blog [http://jitendravyas.com/](http://) was working fine and today I decided to upgrade the Ghost to latest version and I followed the first solution given on this page
But I actually forget to stop the ghost before to run upgrade command. It upgraded but now my site is not working. and Digital Ocean support is unable to help me.
This is the log of /var/log/nginx/error.log http://pastebin.com/UbQfZVe7
Output of some more command which Digital ocean support asked me to share
