Hey Everyone,

I just tried upgrading the newest version of Discourse and unfortunately it did not work.

When I tried logging into my Discourse website with my admin username/password (after the unsuccessful upgrade), I got a message that said “Unknown Message”.

Here is a screenshot:

I’m feeling a bit hopeless. Is there a way to resolve this? Thanks…

Ssh into your server then

```
cd var/discourse
git pull
./launcher rebuild app

```
