Calling $payment_gateways = WC()->payment_gateways->payment_gateways(); problem

Odd; this code returns data, it does not load gateways or change anything.

Where are you calling this? How early?

I have reduced it to to files with minimal code and the results are the same.

class Pay4Pay {
	private static $_instance = null;
	public static function instance(){
		if ( is_null(self::$_instance) )
			self::$_instance = new self();
		return self::$_instance;
	}

	private function __construct() {
	}
}
Pay4Pay::instance();
if ( is_admin() )
	require_once plugin_dir_path(__FILE__) . '/admin/class-pay4pay-admin.php';

Admin file

if ( ! class_exists( 'Pay4Pay_Admin' ) ) :

class Pay4Pay_Admin {

	private static $_instance = null;

	public static function instance(){
		if ( is_null(self::$_instance) )
			self::$_instance = new self();
		return self::$_instance;
	}

	private function __construct() {
		// handle options
		add_action( 'woocommerce_init' , array( &$this , 'add_payment_options'), 99 );
		add_action( 'woocommerce_update_options_checkout' , array( &$this , 'add_payment_options') );

	}

	function add_payment_options( ) {
	var_dump(WC()->payment_gateways()->payment_gateways() );
	}

}

Pay4Pay_Admin::instance();

endif;

That may be too early, before gateways have hooked themselves in. Does it work on a later hook, such as ‘wp’?

I believe wp_loaded instead of woocommerce_init did the trick.
Thanks for the help
