The supported MaximusHost Terraria server runs TShock. TShock is server software that adds administration tools and a plugin system to Terraria.

New servers use Terraria 1.4.5.8 with TShock 6.2.1. Existing servers keep the runtime version they already use; this release does not automatically upgrade them. Check the server's startup output before choosing a plugin, since compatibility depends on both Terraria and TShock versions.

The Plugins tab can add or change plugins only when the saved server runtime is TShock. If an older server uses a runtime without TShock, the tab will explain that; it will not change the runtime for you.

Install a TShock plugin

Open TShock Plugins and stop the server. Upload the plugin's .dll file. You can keep up to 64 plugin files, with a 64 MiB limit per file and 256 MiB total for installed files and saved update copies.

Use Enable or Disable to choose which plugin files TShock will load. Start the server to apply the change. To update a plugin, upload a newer file with the same name and confirm Update. MaximusHost keeps the previous version; if the new file causes trouble, stop the server and choose Restore previous version.

MaximusHost does not scan plugins for safety, verify versions, or automatically install dependencies. Plugin files run code on your server. Use a release from a source you trust, read the author's setup and dependency notes, and check that it supports this server's TShock and Terraria versions. Remove a plugin you no longer want.

Terraria, TShock plugins, and tModLoader

• Terraria is the game and world that your group plays.
• TShock is the server runtime currently provided by MaximusHost. TShock plugins are server-side .dll files.
• tModLoader is a separate modded Terraria runtime. Its mods can change game content and may need matching versions and mod files on every player's client.

TShock plugins are not tModLoader mods. This MaximusHost service does not run tModLoader, Steam Workshop collections, or .twld modded world data. Do not upload tModLoader files to the TShock Plugins tab.

See Troubleshooting if the server does not start after a plugin change.
