Notice: payment_method was called incorrectly

Здравейте,
При следната система:
WordPress version: 5.0.2
WooCommerce version: 3.5.3
получавам следното съобщние за грешка:

Notice: order_total was called incorrectly. Order properties should not be accessed directly. Backtrace: require(‘wp-blog-header.php’), require_once(‘wp-includes/template-loader.php’), include(‘/themes/twentynineteen/page.php’), get_template_part, locate_template, load_template, require(‘/themes/twentynineteen/template-parts/content/content-page.php’), the_content, apply_filters(‘the_content’), WP_Hook->apply_filters, do_shortcode, preg_replace_callback, do_shortcode_tag, WC_Shortcodes::checkout, WC_Shortcodes::shortcode_wrapper, WC_Shortcode_Checkout::output, WC_Shortcode_Checkout::order_pay, wc_get_template, include(‘/plugins/woocommerce/templates/checkout/order-receipt.php’), do_action(‘woocommerce_receipt_epaybg’), WP_Hook->do_action, WP_Hook->apply_filters, WC_Gateway_Epaybg->receipt_page, WC_Gateway_Epaybg->generate_epaybg_form, WC_Abstract_Legacy_Order->__get, wc_doing_it_wrong Please see Debugging in WordPress for more informati in /var/www/html/assyd/wp-includes/functions.php on line 4204

Уж изплаща коректно нещата на https://demo.epay.bg, след разплащане в демо сайта и връщане обратно в магазина получавам:

и транзакцията зависва на “Pending payment”

Това ми показва access.log при отговора от demo.epay.bg:
