Infinite Scroll doesn't load posts

my index.php file has this:

<div id="content">
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post();
        get_template_part('content', get_post_format());
    endwhile; else: ?>
    <p id="no-posts">There's nothing here yet :(</p>
    <?php endif; ?>
</div>

my functions.php file has this:

// theme support for Jetpack infinite scroll
add_theme_support( 'infinite-scroll', array(
	'container'  => 'content',
	'render'    => 'infinite_scroll_render',
	'footer' => false
) );

// render function for Jetpack infinite scroll that 2010 uses, the later WP themes don't need this
function infinite_scroll_render() {
	get_template_part( 'post-loop' );
}

and my post-loop.php has this:

<?php while (have_posts()) : the_post(); ?>
	<article class="teaser">
        (post contents)
	</article>
<?php endwhile; ?>

I don’t see anything that I’m doing wrong?

I tried getting rid of the infninite_scroll_render() function and the post-loop.php file but for some reason nothing changed. It still shows the loading gif but doesn’t load the posts.

If I rename post-loop.php to content-post.php will it load?

my theme uses content.php but when I delete the infinite_scroll_render() function it still doesn’t load the posts.

I just replaced the first line like you said and the posts still arent loading, but now every post looks like a “first” post based on the template.

How do I send you a copy of the theme? I clicked your link but I don’t know how to attach files with that contact form.
