Just found the problem. It′s a version error.
You have to edit the index.php
Change this:
?>
<div id="featured-products" class="<?php if ( get_option( 'woo_featured_product_style' ) == 'slider' ) { echo 'fp-slider'; } ?>">
<h2><?php _e( 'Featured Products', 'woothemes' ); ?></h2>
<ul class="featured-products">
<?php
$args = array( 'post_type' => 'product', 'posts_per_page' => get_option( 'woo_featured_product_limit' ), 'meta_key' => 'featured', 'meta_value' => 'yes' );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); $_product = &new woocommerce_product( $loop->post->ID );
?>
<li class="flipper">
for this:
?>
<div id="featured-products" class="<?php if ( get_option( 'woo_featured_product_style' ) == 'slider' ) { echo 'fp-slider'; } ?>">
<h2><?php _e( 'Featured Products', 'woothemes' ); ?></h2>
<ul class="featured-products">
<?php
$args = array( 'post_type' => 'product', 'posts_per_page' => get_option( 'woo_featured_product_limit' ), 'meta_key' => '_featured', 'meta_value' => 'yes' );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); $_product = &new WC_Product( $loop->post->ID );
?>
<li class="flipper">
