Our discourse is hosted on digitalocean. We don’t use CDN, so I basically followed the instructions _exactly_.

Reading through the instructions again, the only part I could have screwed up is:

> [@Change the domain name or rename your Discourse](https://meta.discourse.org/t/change-the-domain-name-or-rename-your-discourse/16098/1):
>
> ./launcher enter app  
> discourse remap [talk.foo.com](http://talk.foo.com) [talk.bar.com](http://talk.bar.com)  
> rake posts:rebake

I may have typed in

> [@](#):
>
> discourse remap [foo.com](http://foo.com) [bar.com](http://bar.com)

Without the “talk” sub-domain (or in our case “forum” sub-domain). But then again, not everyone puts discourse in a sub-domain, so I would think this is still a bug that could happen to your other customers (and why remap a user’s email?).

Is there a command in ubuntu where I can get command history for that particular command line (after ./launcher enter app)? Then I can confirm this more definitely with you.
