Dear Sirs,

Everything was OK with our JH 1.5.0 (installed via TLJH) but recently our admin added another admin this the following commands:

```auto
sudo tljh-config add-item users.admin otheradmin
sudo tljh-config reload

```

After that I’m unable to start any server on the JH.

Here are the logs and my config:

```auto

Did you or your admin do anything else apart from adding another admin? It sounds like your user environment has become corrupted, the set of packages is no longer consistent.
