Fixed PHP 8.4 Deprecated Warnings

I’m not a PHP coder, but I got tired of waiting for Yoast to fix the most basic stuff, so I’ve learnt and done it for you myself:

/wp-content/plugins/wordpress-seo/vendor_prefixed/symfony/dependency-injection/Container.php on line 60

Change:

    public function __construct(\YoastSEO_Vendor\Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface $parameterBag = null)

To This:

    public function __construct(?\YoastSEO_Vendor\Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface $parameterBag = null)


/wp-content/plugins/wordpress-seo/vendor_prefixed/league/oauth2-client/src/Provider/AbstractProvider.php on line 416

Change:

    public function authorize(array $options = [], callable $redirectHandler = null)

To:

    public function authorize(array $options = [], callable|null $redirectHandler = null)

/wp-content/plugins/wordpress-seo/vendor_prefixed/guzzlehttp/guzzle/src/Client.php on line 181

Change:

    public function getConfig(string $option = null)

To:

    public function getConfig(?string $option = null)


/wp-content/plugins/wordpress-seo/vendor_prefixed/guzzlehttp/guzzle/src/ClientInterface.php on line 77

Change:

    public function getConfig(string $option = null);

To This:

    public function getConfig(?string $option = null);
