the_field not showing

Hello every one!
I have problem.
Code:

<div class="container">
    <div class="row">

      <div class="col-md-12">

        <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

          <div class="page-header">
            <h1><?php the_title(); ?></h1>
            <img class="img-responsive br7" src="<?php the_field('image'); ?>" alt="<?php the_title(); ?>" >
              <p><?php the_field ('description'); ?></p>
              <p><?php the_field ('acc'); ?></p>
             <p><em>
              By <?php the_author(); ?>
              on <?php echo the_time('l, F jS, Y');?>
              in <?php the_category( ', ' ); ?>.
              <a href="<?php comments_link(); ?>"><?php comments_number(); ?></a>
            </em></p>
          </div>

        <?php endwhile; else: ?>

          <div class="page-header">
            <h1>Oh no!</h1>
          </div>
