If you find your server has been griefed, you can go to the Backups tab on your dashboard to see if you have any backups available. We recommend updating your backups as often as possible, especially after completing large builds. The backups you save for your server will be the only ones available to restore your server in the event of damage done to your world. If you need to know more about creating backups, check out this FAQ.
If you know who was responsible, you can find out how to report the player here.
To prevent future griefing on your server, we recommend adding a Whitelist. You can use the command "/whitelist on" to enable the whitelist which will only give users you grant access to the ability to join the server. To add a player to this list, use "/whitelist add (username)".
We also offer a grief protection plugin called Core Protect. This plugin will allow you to roll your server back in the event that you are griefed and need to remove the damage that has been done to your world. You can learn more about it here.
To install Core Protect, please go to your Minehut dashboard and select the Addons tab. Once here, you can search for Core Protect and hit "Install". It's free to download!
