    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
                $this->getServer()->getScheduler()->scheduleRepeatingTask(new shownews($this), 20);
        $this->saveDefaultConfig();
                $this->zeit = 0;
        $this->getLogger()->info(Color::GREEN . "News");
    }

    }    
}
   
?>

can you plz help me?
Sry for my bad English

why you should use Listener in youre timer Task? try to delete the "implements Listener" in the PluginTask class

this

PHP:

public function __construct(Plugin/**/ $owner){//
parent::__construct($owner);
}


should be

PHP:

public function __construct(Main $owner){
parent::__construct($owner);
}

You have to `use pocketmine\plugin\PluginTask;` in your Listener class.

Also, in case you don't, remember that you have to put every class in its independent file.
