Plugins are the easiest way to extend your Minecraft server — permissions, economy, land protection, minigames, and thousands more features — all without your players installing anything. This guide covers installing plugins through the Wasabi Hosting Game Panel, configuring them, and fixing the most common problems.

​
Requirements

Plugins only work on plugin-compatible server software:
  • Paper (recommended — fast and actively maintained)
  • Purpur (Paper fork with extra configuration options)
  • Spigot (the classic plugin platform)
Vanilla, Forge, NeoForge, and Fabric servers cannot load Bukkit/Spigot plugins. If your server isn’t running Paper, Spigot, or Purpur yet, switch in a couple of clicks with the Version Changer.
Forge/Fabric mods and Bukkit plugins are not interchangeable. A .jar from CurseForge’s “Mods” section will not load in your plugins folder — and vice versa.

​
Where to Download Plugins

Only download plugins from trusted sources to avoid malware and broken builds:
SourceURLNotes
SpigotMCspigotmc.org/resourcesLargest plugin repository
Hangarhangar.papermc.ioPaperMC’s official platform
Modrinthmodrinth.com/pluginsModern, fast, open source
Bukkit / CurseForgedev.bukkit.orgOlder catalog, still useful
Always check the plugin page for supported Minecraft versions before downloading. A plugin built for 1.8 will usually fail on a modern server.

​
Installing a Plugin

1

Download the plugin .jar

Download the plugin’s .jar file from one of the sources above, matching your server’s Minecraft version.
2

Open the File Manager

In the Game Panel, select your server and open the File Manager. You can also connect via SFTP — see File Management for both methods.
3

Upload to the plugins folder

Navigate to the /plugins directory and upload the .jar file. If the folder doesn’t exist yet, start the server once on Paper/Spigot and it will be created automatically.
4

Restart the server

Restart (not just reload) the server from the panel so the plugin loads cleanly.
5

Verify it loaded

In the panel Console, run:
plugins
Loaded plugins appear in green; plugins that failed to load appear in red. If a plugin is red or missing, check the console log for the error.

​
Configuring Plugins

Most plugins generate their own configuration folder the first time they load: 
/plugins/
├── EssentialsX.jar
├── EssentialsX/          <- generated config folder
│   └── config.yml
├── LuckPerms.jar
└── LuckPerms/
    └── config.yml
Edit the config.yml (or other files) inside the plugin’s folder using the File Manager, then restart the server — or use the plugin’s own reload command if it has one (for example /ess reload for EssentialsX).
YAML files are indentation-sensitive. Use spaces (never tabs), and keep the existing indentation when editing.

​
Updating and Removing Plugins

  1. Stop the server (or plan a restart).
  2. Delete the old .jar from /plugins — leave the plugin’s config folder in place so your settings are kept.
  3. Upload the new .jar and start the server.
  4. Check the console for migration messages; some updates rewrite their config files.
  1. Stop the server.
  2. Delete the plugin’s .jar from /plugins.
  3. Optionally delete its config folder too (only if you don’t plan to reinstall it).
  4. Start the server again.
Before bulk plugin changes, create a backup from the panel’s Backups tab so you can roll back instantly. See Backups.

​
Common Issues

Usually a Minecraft version mismatch. Check the console for UnsupportedClassVersionError or “This version of the plugin is not compatible” messages, and download a build that matches your server version.
Many plugins require libraries such as Vault, PlaceholderAPI, or ProtocolLib. The console will name the missing plugin — install it the same way and restart.
Confirm the file is directly in /plugins (not in a subfolder or still zipped), the file ends in .jar, and your server is actually running Paper/Spigot/Purpur — check with the Version Changer.
Remove the most recently added plugin and restart. If the server recovers, check that plugin’s version compatibility or look for a known conflict on its resource page. More help in Troubleshooting.
Too many plugins can also affect performance — see the Optimization guide for tips on keeping your TPS high.
