MaximusHost Terraria servers run TShock, which supports server-side plugins. TShock plugins are not tModLoader mods; this service does not run tModLoader.
Before installing
Check the server’s Terraria and TShock versions in startup output. At the time of this post, new servers use Terraria 1.4.5.8 with TShock 6.2.1; existing servers keep their current runtime. Terraria and TShock can be updated to a current revision by stopping and starting the game server. Confirm that the plugin supports both versions and read the publisher’s setup and dependency notes.
Plugin files run code on your server. MaximusHost does not scan files for safety, confirm compatibility, or install dependencies for you. Download only from a source you trust and make a full-server backup before changing plugins.
Upload and enable a plugin
- Stop the server and open TShock Plugins.
- Upload the plugin’s `.dll` file. The manager allows up to 64 plugin files, 64 MiB per file, and 256 MiB total for installed files and saved update copies.
- Use Enable for the plugin you want TShock to load. Disable plugins you do not want loaded.
- Start the server and review Console for startup errors before inviting players.
Changes are applied when the server starts. Add one plugin at a time so you can identify which change caused a problem.
Update or roll back
To update: stop the server, upload the newer file with the same name, and confirm Update. MaximusHost saves the previous version. If the new release causes trouble, stop the server and choose Restore previous version, then start the server and check Console again.
To remove a plugin you no longer need, stop the server and use the plugin manager’s remove action. Keep a backup before making changes to an established server.
Troubleshooting
If the server fails to start after a plugin change, find the first relevant error in Console. Stop the server and disable the newest plugin, or restore its previous version. Check its version requirements and dependencies before trying again. Restore a full-server backup only if you need to recover a broader earlier state; a restore replaces current server files.
MaxiomusHost offers use of an AI powered Diagnostic that may help. This function is found on the server management page.
