 * Hallo
    I saw in the error_log file that the plugin produces this message:
 * [20-Dec-2017 12:31:47 UTC] price was called incorrectly. Non puoi accedere direttamente
   alle proprietà del prodotto. Backtrace: require(‘wp-blog-header.php’), require_once(‘
   wp-load.php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’),
   do_action(‘wp_loaded’), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array,
   WC_Cart_Session->get_cart_from_session, WC_Cart->calculate_totals, WC_Cart_Totals-
   >__construct, WC_Cart_Totals->calculate, WC_Cart_Totals->calculate_fee_totals,
   WC_Cart_Totals->get_fees_from_cart, WC_Cart->calculate_fees, do_action(‘woocommerce_cart_calculate_fees’),
   WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, WooCommerce_Product_Fees-
   >add_fees, WC_Abstract_Legacy_Product->__get, wc_doing_it_wrong. This message
   was added in version 3.0.
 * My plugin version is 3.2.3
    How can I solve this problem?
 * Thanks

 * Hi [@gdm57](https://wordpress.org/support/users/gdm57/),
 * It seems that this error comes not from Booster, but from some plugin with `WooCommerce_Product_Fees`
   class. Could you please recheck?
 * Best regards,
    Tom

 * Thanks for answer: You helped me, thank you.
    I tried without that plugin (WooCommerce_Product_Fees),
   and Booster does not produce any error_log file. Was the other plugin to give
   error. Thanks a lot
