Solved Plugin not working?

I'm coding a plugin, but isn't working at all. Please help me fix and explain my mistakes (I want to learn too).
I'm not getting any errors.

PHP:

<?php

use pocketmine\command\Command;
use pocketmine\event\Listener;

use pocketmine\Player;
class Main extends PluginBase implements Listener {
    
    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->saveDefaultConfig();
    }
    
    public function onCommand(CommandSender $sender, Command $cmd, $label, array $args) {
        switch($cmd->getName()) {

Are you sure your code is even being executed? Use var_dump().
Anyway, I found a possible fault in your code. You forgot to save the config after modifying it.

 

How do I save it?

 

Oh, I forgot that. But why can players still open the Crafting Tables?

 

Your code might not be fully executing. Can you provide the level name and the config file?

 

That means, it's not possible to completely block crafting (except the Crafting Tables)?

 

could the server remove the window after it opens?
