Overview of the issue

When translating taxonomies that are set as child of some parent category, the hierarchy of child- parent categories is not synced to translated categories.

Workaround

Please, make sure of having a full site backup of your site before proceeding.


  • Edit the …/wp-content/plugins/sitepress-multilingual-cms/inc/wpml-post-edit-ajax.class.php

  • Look for line 18

  • Replace:global $sitepress;

  • With:global $sitepress, $wpdb;

  • Then, just before the line:$sitepress->get_wp_api()->wp_send_json_success( $new_term_object );

  • Add the following code:$sync = new WPML_Term_Hierarchy_Sync($wpdb);
    $sync->sync_element_hierarchy($taxonomy);
