If your site is down, I will fix it. I will see that all OS updates are done, and that you are running the latest version of Discourse. If your problem is due to an errant plugin, it will be disabled.
NOTE: If your site’s OS is beyond its end of life, or your Discourse installation is so old that the database needs to be migrated from an earlier version of Postgres, extra charges may be required.
To complete this process I need ssh access to your server. The best way to provide this is usually to issue the following command and then tell me the hostname, user, and port (if not 22) to access the server.
