Call to undefined function rwmb_get_registry() - Frontend Submission

Hello

When i use this shortcode

echo do_shortcode( '[mb_frontend_form id="personal"]' );

when Frontend Submission is installed i get

Fatal error: Call to undefined function rwmb_get_registry() in /home/ubuntu/workspace/wp-content/plugins/mb-frontend-submission/inc/class-mb-frontend-form-shortcode.php on line 91

error.

And the sample metabox is

	$meta_boxes[] = array(
		'id'         => 'personal',
		'title' => esc_html__( 'İç Özellikler', 'your-prefix' ),
		'post_types' => array( 'emlak' ),
		'class'   => 'emlak_icozellikler',
		'hidden' => array( 'emlak_tipi', '!=', 'konut' ),
		'fields' => array(
			array(
				'name'    => esc_html__( 'İç Özellikleri Seçin', 'your-prefix' ),
				'label_description' => esc_html__( 'Birden fazla İç Özellik seçebileceğinizi unutmayın', 'your-prefix' ),
				'id'      => "icozellik",
				'type'    => 'checkbox_list',
				
				//'field_type' => 'checkbox_list',
			
				// Array of 'value' => 'Label' pairs for radio options.
				// Note: the 'value' is stored in meta field, not the 'Label'
				'options' => array(
					'1' => esc_html__( 'ADSL', 'your-prefix' ),

				),
			),
		),
	);
