my blog http://jitendravyas.com/ was working fine and today I decided to upgrade the Ghost to latest version and I followed the first solution given on this page
http://www.allaboutghost.com/how-to-update-ghost-to-version-0-4/
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.
