In another thread I found a solution (see code below) to move the WooCommerce product tabs to below the short description and image gallery, and fill the width of the page.
It seemed to work for the person in the original thread, but for me, the description now appears below the ‘Related Products’ which doesn’t really work!
Any suggestions?
========================================================
add_action( ‘init’, ‘wooDescription’, 10 );
function wooDescription() {
remove_action( ‘woocommerce_single_product_summary’, ‘woocommerce_output_product_data_tabs’, 31 );
add_action( ‘woocommerce_after_single_product’, ‘woocommerce_output_product_data_tabs’, 10 );
}
