  • Spigot/Paper configuration files
  • BungeeCord/Velocity configs
  • Permission plugin files (LuckPerms, etc.)

Frequently Asked Questions

Why won't my plugin load?

Most plugin loading failures are caused by YAML syntax errors in config files. Paste your config here to find the exact error location.

What's wrong with using tabs?

YAML requires spaces for indentation, not tabs. Many text editors insert tabs by default, which causes parsing errors. Always use 2 spaces.

How do I fix "special character" errors?

Wrap values containing special characters like @, *, !, or & in quotes. For example: message: "&aHello World"

Can I validate JSON configs?

Yes! Click the JSON tab to switch formats. The parser will validate JSON syntax and can also prettify/format your JSON files.
