    Please see the link below:

    In the widgets area on the right side, I am getting the error:

    Warning: Invalid argument supplied for foreach() in /home/content/04/9655804/html/wp-content/themes/parallelus-salutation/functions.php on line 271

    The code in these lines are as follows:

    function qa_widget_show_sub_cats( $cat_args, $instance ) {
	global $post;
	if ( is_qa_page() ) {
		$cats = get_the_terms( $post->ID, 'question_category' );
		foreach ( $cats as $category ) {
			if ( $category->term_id ) {
				$termchildren = get_term_children( $category->term_id, 'question_category' );
				if ( $termchildren && !empty( $termchildren ) && !is_object( $termchildren )  ) {
					$cat_args['child_of'] = $category->term_id;
					break;
				}
			}
		}
	}
	return $cat_args;
}

    Could you please help me figure out where is the problem?

    happens if there is no $cats found;

    edit the section to include a conditional check:

    $cats = get_the_terms( $post->ID, 'question_category' );
		if( $cats ) foreach ( $cats as $category ) {
