{% endstep %}
{% endstepper %}

### Common issues

* **Server does not start after change** : wrong Java version or wrong build.
* **Plugins not loaded** : you might be on Vanilla/Forge. Bukkit/Spigot plugins require Paper/Spigot.
* **World “reset”** : the world folder has changed (see `level-name`).

### FAQ

#### Paper, Spigot, Forge: which should I choose?

* **Paper** : recommended for its performance and plugins.
* **Spigot** : plugins, more “vanilla-like”.
* **Forge** : mods (not classic Bukkit plugins).
