[Plugin: WooCommerce – excelling eCommerce] remove description and review page

The tabs (including corresponding panels) are added by the following actions:

add_action( 'woocommerce_product_tabs', 'woocommerce_product_description_tab', 10 );
add_action( 'woocommerce_product_tabs', 'woocommerce_product_attributes_tab', 20 );
add_action( 'woocommerce_product_tabs', 'woocommerce_product_reviews_tab', 30 );
add_action( 'woocommerce_product_tab_panels', 'woocommerce_product_description_panel', 10 );
add_action( 'woocommerce_product_tab_panels', 'woocommerce_product_attributes_panel', 20 );
add_action( 'woocommerce_product_tab_panels', 'woocommerce_product_reviews_panel', 30 );

You can remove all of them, by reversing this add_action() function and using remove_action() calling with the same arguments. For example to remove the reviews tab and panel:

remove_action( 'woocommerce_product_tabs', 'woocommerce_product_reviews_tab', 30 );
remove_action( 'woocommerce_product_tab_panels', 'woocommerce_product_reviews_panel', 30 );

This code should go in your (child) themes functions.php, or create a plugin out of it.
