Install the plugin

Download the jar, check TrainCarts and WorldGuard are there, start your server once.

Updated 16 October 2026

Check your server first#

Plugin or software	Version you need
Paper	1.20.4 or newer
Java	whatever your server already runs on (17 or newer)
TrainCarts and BKCommonLib	2.0.0 or newer
WorldGuard (with WorldEdit)	the version made for your Minecraft version
TC-Coasters	optional — only if you build your tracks with it, or for a transfer table
PlaceholderAPI	optional, 2.11.6 or newer — only for the placeholders

Spigot, Folia and other server types are not supported: Ultimate Theme Park needs Paper.

Put the plugin on your server#

Download the latest UltimateThemePark-….jar from your downloads.
Put it in your server's plugins folder, next to TrainCarts and WorldGuard.
Start (or restart) your server.

"The plugin disabled itself" — that's expected#

On this first start, the console shows something like this:

[UltimateThemePark] [config] cannot start, configuration is incomplete:
[UltimateThemePark] [config]   - license-key is missing: paste the key you received by e-mail after purchase
[UltimateThemePark] [config]   - connect.secret is missing: it is printed when the container starts for the first time
[UltimateThemePark] [config] fix plugins/UltimateThemePark/config.yml, then restart the server

Nothing is wrong. The plugin has created its folder, plugins/UltimateThemePark/, with a config.yml inside, and it waits for you to fill it in. You will do that in Link your server, once UTP Connect is running.

What's in the plugin's folder#

File	What it is
`config.yml`	Three values: your license key, the address of UTP Connect, and a secret. That's all.
`lang/`	The in-game messages, in six languages. You can edit them — see Make it yours.
`instance-id`	Your server's identity for the license. Don't copy it to another server.
`license.cache`	Lets the plugin keep running if our license service is unreachable.

Next step: Install UTP Connect.
