Custom Post Type not showing

After checking for the “Hide content that’s not avalable for selected languages” one of my custom post_types (that has only title, thumbnail and custom fields) does not show in my page.
Here’s the code:
At functions.php:

$args = array(
		'public' => true,
		'label'  => 'Banners',
		'menu_position' => 5,
		'supports' => array('title', 'thumbnail')
    );
    register_post_type( 'banner', $args );

At index.php

<?php
	            	$args = array(
	            		'post_type' => 'banner',
	            		'posts_per_page' => 5,
	            		'post_status' => 'publish'
	            		);
	            	$banner = new WP_Query($args);

	            	//var_dump($banner);

	            	if($banner->have_posts()):
	            	?>
	                <div class="col-sm-12 flexslider banner">
	                    <ul class="slides">
	                    	<?php while($banner->have_posts()): $banner->the_post();?>
	                    		<?php $hover_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');?>
	                    		<?php
	                    		//echo get_field('tipo_link');
	                    		$target = "_self";
	                    		if(get_field('tipo_link') != 'false'){
	                    			$tipo = get_field('tipo_link');
	                    			$url = get_field("link_{$tipo}");
	                    			if($tipo == 'externo'){
	                    				$target = "_blank";
	                    			}
	                    		}else{
	                    			$url = 'javascript:void(0)';
	                    		}
	                    		//echo $url;
	                    		?>
		                        <li><a href="<?php echo $url;?>" target="<?php echo $target;?>">
		                        	<img src="<?php echo $hover_url[0];?>" alt="<?php the_title();?>">
		                        	<div class="title-bg"><h3><?php the_title();?></h3></div>
		                        </a></li>
		                    <?php endwhile;?>
	                    </ul>
	                </div>
	                <?php endif;wp_reset_postdata();?>
