Localization isn’t working for me

[I’ve done everything according to the documentation, using AdminLTE, and my code is in the template:

...
    <div class="row form__group mb-3 mt-3">
        <label class="col-md-3">Основное фото статьи</label>
        <div class="col-md-3">
            <button id="lfm" data-input="thumbnail" data-preview="holder" class="btn btn-primary btn-block">
                <i class="fa fa-picture-o"></i> Выбрать
            </button>
            <input id="thumbnail"
                   class="form-control"
                   type="hidden"
                   @if ($model->exists) value="{{ $model->general_photo }}" @endif
                   name="general_photo">
        </div>
    </div>

    <div class="form__group">
        <div id="holder" style="margin-top:15px; max-height:100px;">
            @if ($model->exists)
                <img src="{{ $model->general_photo }}" style="height: 100px" width="100px">
            @endif
        </div>
    </div>

    <div class="form__group">
        <label>Статья статической страницы RU</label>
        {{ Form::textarea('description_ru', null, ['class' => 'form-control', 'id' => 'description_ru']) }}
    </div>
...
@push('js')
    <script src="{{ asset('/vendor/laravel-filemanager/js/stand-alone-button.js') }}"></script>

    <script type="text/javascript">
        var options = {
            filebrowserImageBrowseUrl: '/ing/laravel-filemanager?type=Images',
            filebrowserImageUploadUrl: '/ing/laravel-filemanager/upload?type=Images&_token={{ csrf_token() }}',
            filebrowserBrowseUrl: '/ing/laravel-filemanager?type=Files',
            filebrowserUploadUrl: '/ing/laravel-filemanager/upload?type=Files&_token={{ csrf_token() }}'
        }


        CKEDITOR.replace('description_ru', options);
        CKEDITOR.replace('description_ua', options);

        $(document).ready(function () {
            $('#lfm').filemanager('image', {'prefix': '/ing/laravel-filemanager'});
        });
    </script>
@endpush

In config/app.php, I changed 'locale' => 'ua' to 'locale' => 'ru', and everything started working.
