Infinite Scroll Plugin sadly doesnt work.

Hello guys, i cant find out why the Infinite Scroll Plugin doesnt work for me.
Homepage is: https://184990.webhosting29.1blu.de/sportsbuddies/
I have no idea why.

Functions.php:

<?php
add_filter( 'show_admin_bar', '__return_false' );
add_theme_support( 'infinite-scroll', array(
    'container' => 'content',
) );
?>

Index.php:

<?php get_header(); ?>

   <div id="content"> 

    <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
	<div id="post">
			 	<div id="meta">
				<h2 class="author-avatar"><?php echo get_avatar( get_the_author_meta( 'ID' ), 50 ); ?><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
				<p class="author-meta"><?php the_author('display_name'); ?>
				am: <?php the_time('d.F.Y'); ?></p>
               </div>

            <?php the_content(); ?>

		 </div> <!--post-->
      <?php endwhile; endif; ?>

   </div><!-- content -->

<?php get_footer(); ?>

Thank you so much
