Problem after updating to Royal 3.0.1 and WC 3.0.0

Hello, @thorth219,

Please use our last theme version and WooCommerce 3.0.1 http://prntscr.com/eum0vh.
Also, try to disable 3-rd party plugins and then check your issues.
Let us know the result.

Rose Tyler.

I have a problem with the checkout page after the updating. Fatal error: Can’t use method return value in write context in wp-content/themes/royal/woocommerce/checkout/form-billing.php on line 48

How can i solve this, please?

Hello, @thorth219,

To solve problem, please change /royal/woocommerce/single-product/add-to-cart/simple.php file to:

<?php
/**
 * Simple product add to cart
 *
 * @author 		WooThemes
 * @package 	WooCommerce/Templates
 * @version     3.0.0
 */

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

global $woocommerce, $product;

if ( ! $product->is_purchasable() ) return;
?>

<?php
	// Availability
	$availability      = $product->get_availability();
	$availability_html = empty( $availability['availability'] ) ? '' : '<p class="stock ' . esc_attr( $availability['class'] ) . '">' . esc_html( $availability['availability'] ) . '</p>';
	
	echo apply_filters( 'woocommerce_stock_html', $availability_html, $availability['availability'], $product );
?>

<?php if ( $product->is_in_stock() ) : ?>

	<?php do_action( 'woocommerce_before_add_to_cart_form' ); ?>

	<form class="cart" method="post" enctype='multipart/form-data'>
	 	<?php do_action( 'woocommerce_before_add_to_cart_button' ); ?>

	 	<?php
	 		if ( ! $product->is_sold_individually() )

	 		/**
			 * @since 3.0.0.
			 */
			do_action( 'woocommerce_before_add_to_cart_quantity' );

	 			woocommerce_quantity_input( array(
	 				'min_value' => apply_filters( 'woocommerce_quantity_input_min', 1, $product ),
	 				'max_value' => apply_filters( 'woocommerce_quantity_input_max', $product->backorders_allowed() ? '' : $product->get_stock_quantity(), $product )
	 			) );

	 		/**
			 * @since 3.0.0.
			 */
			do_action( 'woocommerce_after_add_to_cart_quantity' );
	 	?>

	 	<input type="hidden" name="add-to-cart" value="<?php echo esc_attr( $product->get_id() ); ?>" />

	 	<button type="submit" name="add-to-cart" value="<?php echo esc_attr( $product->get_id() ); ?>" class="single_add_to_cart_button <?php if(etheme_get_option('ajax_addtocart')): ?>etheme-simple-product<?php endif; ?> button alt"><?php echo $product->single_add_to_cart_text(); ?></button>

		<?php do_action( 'woocommerce_after_add_to_cart_button' ); ?>
	</form>

	<?php do_action( 'woocommerce_after_add_to_cart_form' ); ?>

<?php endif; ?>
