Problem with tag page

Hi to all.

I have a problem with tag page. This is the code of the page:

<?php get_header();
	$vbegy_sidebar_all = vpanel_options("sidebar_layout");
	$tag_des           = vpanel_options('tag_description');
	$post_style        = vpanel_options("post_style");
	if ($tag_des == "on") {
		$tag_description = tag_description();
		if (!empty( $tag_description)) {?>
			<div class="v-post post-style-2 category-description">
				<div class="post-wrap">
					<div class="post-inner">
						<div class="post-title">
							<?php echo __("Tag","vbegy").": ".esc_attr(single_tag_title("", false));
							$tag_rss = vpanel_options("tag_rss");
							if ($tag_rss == "on") {?>
								<a href="<?php echo esc_url(get_tag_feed_link(esc_attr(get_query_var('tag_id'))))?>"><i class="fa fa-rss"></i></a>
							<?php }?>
						<span class="post-point"></span></div><div class="clearfix"></div>
						<?php echo ($tag_description); ?>
					</div><!-- End post-inner -->
				</div><!-- End post-wrap -->
			</div><!-- End post -->
		<?php }
	}
	$args = array(
 		'post_type' => array ( 'post', 'recipe','video'),
		'tag__in' => get_query_var('tag_id'),
		'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1 ),
		'posts_per_page' => 30
	);
	get_template_part("loop","tag");
	get_template_part("includes/pagination");
	wp_reset_query();
get_footer();?>

I need to show 3 post type with the same tag, but with this code it doesn’t work. Other pages work correcty.

how can I solve this problem?
