Symptoms: Unknown command, the command is not recognised, nothing happens when you type /, command not found

Possible Causes

  • The plugin that provides the command is not loaded or failed with an error
  • The wrong command syntax is being used
  • The permission required to run the command is missing
  • Another plugin has overwritten the same command alias

Step-by-Step Fix

Step 1

Check that the plugin providing the command is installed and enabled

bash
/plugins

Step 2

Look up the correct syntax with the plugin's help command

bash
/help <plugin_ismi>

Step 3

Pin down the permission problem with LuckPerms verbose

bash
/lp verbose on

Step 4

Check for an alias conflict — an override may be defined in commands.yml

bash
cat commands.yml

Step 5

Check whether the plugin is throwing errors in the console

bash
grep -i "error\|exception" logs/latest.log | tail -20
