Почему я не могу опубликовать пост через wp-recall?

Я использую стандартный wp-recall
Без сторонних дополнений кроме Webmoney Gateway
После обновления wp-recall в console начала появляться такая ошибка

core.js?ver=16.17.11:942 Uncaught TypeError: Cannot read property '0' of undefined

Хорошо я нашел проблему в теме.
Вот код вызывающий проблемы

add_filter('rcl_public_form_fields', 'add_pole', 10, 2);
function add_pole($fields, $formData){
$fields[] = array(
	'type' => 'custom',
	'slug' => 'desc_cat',
	'title' => __('Категорий поста'),
	'content'=>'<textarea type="file" id="desc_cat_id" name="cat_name" ></textarea>'
);
return $fields;
}
