Soluzione alternativa

Assicurati di avere un backup completo del tuo sito prima di procedere.

• Apri il file …/acfml/classes/class-wpml-acf-repeater-shuffle.php.
• Cerca la riga 244.
• Sostituisci:

  private function isChildOfRepeaterField( $key, $postId ) {
  	$acfFieldObject = get_field_object( $key, $postId );
  	if ( isset( $acfFieldObject['parent'] )
  		 && $acfFieldObject['parent'] > 0 ) {
  		$fieldParent        = get_post( $acfFieldObject['parent'] );
  		$fieldParentContent = maybe_unserialize( $fieldParent->post_content );
  		if ( isset( $fieldParentContent['type'] ) && 'repeater' === $fieldParentContent['type'] ) {
  			return true;
  		}
  	}
  	return false;
  }

• Con:

  private function isChildOfRepeaterField( $key, $postId ) {
      $acfFieldObject = get_field_object( $key, $postId );
      if ( isset( $acfFieldObject['parent'] ) ) {
          if ( is_numeric( $acfFieldObject['parent'] ) && $acfFieldObject['parent'] > 0 ) {
              $fieldParent = get_post( $acfFieldObject['parent'], $postId );
              if ( $fieldParent ) {
                  $fieldParentContent = maybe_unserialize( $fieldParent->post_content );
                  if ( isset( $fieldParentContent['type'] ) && 'repeater' === $fieldParentContent['type'] ) {
                      return true;
                  }
              }
          } elseif ( is_string( $acfFieldObject['parent'] ) ) {
              $fieldParent = get_field_object( $acfFieldObject['parent'], $postId );
              if ( isset( $fieldParent['type'] ) && 'repeater' === $fieldParent['type'] ) {
                  return true;
              }
          }
      }
      return false;
  }
