Hello,
I’ve edited the file wp-content/themes/royal/framework/woo.php in line 1297 and replaced the code code with this one:
$product_price = get_option( 'woocommerce_display_cart_prices_including_tax' ) == 'yes' || $woocommerce->customer->is_vat_exempt() ? $_product->get_price_including_tax() : $_product->get_price_including_tax();
Clear browser cache and check Cart popup window now.
Regards,
Eva Kemp.
