# Update | 1.21.8 to 1.21.11

{% hint style="info" %}
Update released: 07th February 2026
{% endhint %}

<mark style="color:orange;">**Start by downloading the latest version of the setup you are using on BuiltByBit.**</mark>

<mark style="color:red;">**Before completing all the step below, please STOP your server to avoid any file corruption!**</mark>

***

## 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`
