Problem:
When cancelling a WooCommerce Booking in wp-admin, a fatal error occurs related to the cancellation email. This issue is due to a conflict between WooCommerce Multilingual & Multicurrency and WPML Multilingual CMS.

Solution:
We recommend modifying the code in the WooCommerce Multilingual plugin to handle null values correctly. Specifically, in the file

wp-content/plugins/woocommerce-multilingual/compatibility/WcBookings/class-wcml-bookings.php

, make the following changes:

1. For the method

\WCML_Bookings::get_translated_booking_resource_id

around line 948, replace:

if (is_null($trnsl_booking_resource_id)) {<br />    $trnsl_booking_resource_id = '';<br />}

with:

if (is_null($trnsl_booking_resource_id)) {<br />    $trnsl_booking_resource_id = $booking_resource_id;<br />}

2. Similarly, for

WCML_Bookings::get_translated_booking_product_id

around line 932, change:

if ($booking_product_id) {<br />    $trnsl_booking_product_id = apply_filters('translate_object_id', $booking_product_id, 'product', false, $language);<br />    if (is_null($trnsl_booking_product_id)) {<br />        $trnsl_booking_product_id = $booking_product_id;<br />    }<br />}

If this solution does not resolve your issue or seems irrelevant due to updates or different circumstances, please check the related known issues and confirm that you have installed the latest versions of themes and plugins. If the problem persists, we highly recommend opening a new support ticket at WPML support forum.
