Advanced Custom Fields Multilingual - ACF taxonomy field does not load terms

Overview of the issue

Since our recent ACFML 2.0 update, the ACF function for taxonomy fields called Load Terms is not working properly. As a result, when you save a post custom field with this function, the term may be set, but the field will remain empty.

Workaround

Be sure to make a full backup of your site before proceeding. Then, to work around this issue, you can apply the following patch to the Advanced Custom Fields Multilingual plugin:

1. Open the file /wp-content/plugins/acfml/classes/strategy/repeater-sync/HooksFactory.php in a text editor.
2. Look for line 10.
3. Replace the following code:

   1 2 3 4 5 6

   class HooksFactory implements IWPML_Backend_Action_Loader {       /**      * @return IWPML_Action[]      */     public function create() {

   With:

   1 2 3 4 5 6 7 8 9 10 11 12 13

   class HooksFactory implements IWPML_Backend_Action_Loader, IWPML_Deferred_Action_Loader {       /**      * @return string      */     public function get_load_action() {         return 'wp_loaded';     }       /**      * @return IWPML_Action[]      */     public function create() {
