PHP Code – FATAL ERROR

Hi there,

We would like to show Reviews as default on our Woo Commerce Single Product page. We were told by yourselves to paste this code at the bottom of the functions.php file. We just did and it broke the whole site! The code we were sent is:

add_filter( 'woocommerce_product_tabs', 'sb_woo_move_description_tab', 98);
function sb_woo_move_description_tab($tabs) {
$tabs['reviews']['priority'] = 1;
return $tabs;
}

We would still like Reviews to show as default (instead of Description). Your help, as always, would be much appreciated.

Thanks,

Robert
