Hi,

You need to add this hook in functions.php

add_action('woocommerce_after_add_to_cart_button', 'woocommerce_after_add_to_cart_button_epofw_nonce', 10);
function woocommerce_after_add_to_cart_button_epofw_nonce(){
if ( class_exists( 'EPOFW_Front' ) ) {
global $post;
$epofw = new EPOFW_Front;
$main_fields_data_arr = $epofw->epofw_get_fields_data( $post->ID );
    if ( empty( $main_fields_data_arr ) ) {
        wp_nonce_field( 'epfow_addon_field_nonce_' . $post->ID );
    }
}
}
