is_user_logged_in() affects unrelated content

I’m using is_user_logged_in() in sidebar.php. Everything in sidebar.php works fine but, if a visitor is not logged in, get_content() in home.php does not happen

sidebar.php:

<?php if ( is_user_logged_in() ) : ?>
some html
<?php else: ?>
other html
<?php endif; ?>

_____________
home.php:

<?php get_header(); ?>
<?php get_sidebar(); ?>
<div id=”main-content”>
<?php the_content(); ?>
</div>
<?php get_footer(); ?>
