Update | 1.21.8 to 1.21.11

This guide explains how to update any of our Premium setups from 1.21.8 to 1.21.11. If your setup is currently on 1.21.8, this is the guide you should follow.

Update released: 07th February 2026

Start by downloading the latest version of the setup you are using on BuiltByBit.

Before completing all the step below, please STOP your server to avoid any file corruption!

1. Updating the JAR

The first step is to update your server JAR. We recommend using Paper, so make sure to update to the latest 1.21.11 version of PaperMC: https://papermc.io/

2. Updating the Plugins

The next step is to update all plugins in the setup. The easiest way is to download the latest version of your setup from BuiltByBit. Then, delete the existing plugins on your server (except for any you added yourself) and upload the plugins from the latest setup version.

You also have to update all dependencies.

3. Updating ExcellentCrates

The latest version of ExcellentCrates introduced several changes that require the ExcellentCrates configuration files in the setup to be reconfigured. Therefore, you need to delete the ExcellentCrates plugin folder on your server and replace it with the ExcellentCrates plugin folder from the latest version of the setup.

This also has to be done with the ExcellentCrates files from the Dungeons and RPG Addons.

4. Fixing "Server is full!"

The 1.21.11 update caused an issue with the Essentials plugin that prevents players from joining the setup. To fix this, set use-custom-server-full-message to false in the Essentials config.yml. This setting is located around line 571. You can find the file at: plugins > Essentials > config.yml.

5. Fix for CoinsEngine

For 1.21.11, CoinsEngine had to be updated, which caused some issues. The take command in the plugin was changed to remove, which creates problems for DeluxeMenus menus that still use the take command. To fix this, upload this file to the following filepath on your server: plugins > CoinsEngine

commands.yml
