Overview of the issue

When importing variable products with WP All Import and the WPML All Import add-on on a server running PHP 8, you will see the following error:

PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class WCML_Synchronize_Product_Data does not have a method “delete_empty_post_meta_for_translations” in /wp-includes/class-wp-hook.php:309

In PHP 7.0, this error displays as a warning.


Please make a full backup of your site before proceeding.

  1. Open the …/wp-content/plugins/wpml-all-import/classes/WCML.php file.
  2. Look for line 35 and comment it out:
    //remove_action( 'deleted_post_meta', [ $WCMLSynchronizeProductData, 'delete_empty_post_meta_for_translations' ], 10, 3 );
  3. Do the same with line 46:
    //add_action( 'deleted_post_meta', [ $this->getWCMLSynchronizeProductData(), 'delete_empty_post_meta_for_translations' ], 10, 3 );
