ERROR: your account key is missing, please reconnect your server to SimpleBackups (ES900).
An ES900 error means that the working directory for SimpleBackups on the server has been deleted or changed. This requires that you re-connect a server by either clicking the "Validate Connection" or by re-running the connection script again.
Pleas note that it is not recommended to use
/tmp as a working directory for your server because the
/tmp directory might be cleared out by the OS and is meant for temporary data only.
