Background of the issue:
I was trying to access the orders list after updating to the RC 5.4.0-rc.1 update. The issue is caused by the woocommerce-multilingual plugin. Here is the error trace: An error of type E_ERROR was caused in line 52 of the file /home/html/adm.dental/_sub/beta/wp-content/plugins/woocommerce-multilingual/classes/OrderItems/Shipping/ShippingMethod.php. Error message: Uncaught Error: Call to a member function get_title() on bool in /home/html/adm.dental/_sub/beta/wp-content/plugins/woocommerce-multilingual/classes/OrderItems/Shipping/ShippingMethod.php:52. It seems that it is caused by this code: $shippingMethod = WC_Shipping_Zones::get_shipping_method( $shippingInstanceId ); if ( $shippingTitle === $shippingMethod->get_title() ) { $item->set_method_title( $this->woocommerce_wpml->shipping->translate_shipping_method_title( $shippingTitle, $shippingId . $shippingInstanceId, $targetLanguage ) ); return; } get_shipping_method( $shippingInstanceId ); returns false, because it did not found the shipping method as described here: hidden link::get_shipping_method. Link to a page where the issue can be seen: hidden link
Symptoms:
I encountered a critical error in the orders panel, specifically a 'Call to a member function get_title() on bool' fatal error. I expected to see a list of orders but only saw the first two orders, then half of #2277 where the error occurred.
- Make sure you have a backup.
- Disable all other plugins and leave active only WPML plugins and Wocommerce
- Switch to WP default theme
- Check if the issue still happens.
2) If the issue still happens, please create a staging site and share admin access with us so we can further check and escalate this issue. Note we might need to take a copy of your site, let me know if that is not okay.
Yes, the issue is caused by WCML. “PPL na adresu” is a shipping method included in the PPL plugin. Once you activate the plugin, you can configure this method in WooCommerce shipping settings: hidden link
