theme everbox get category displayed with author and date

Hi,

i am not a hero in css and php, i made a simple wiki for my own personal use and now i wanted to get the category displayed in the blog page on the same line as the author and date.

I have managed to get it displayed but not on the right position, this is what it looks now:

Linux >
process status and uptime

beheerder ? 3 december 2015 ? No Comment ? <HERE THE CATEGORY SHOULD BE>

get process properties status and uptimeps -eo pid,comm,cmd,start,etime | grep -i apache

This is the index.php where also the post-id loop is:
<?php
/**
* The main template file.
*
* This is the most generic template file in a WordPress theme
* and one of the two required files for a theme (the other being style.css).
* It is used to display a page when nothing more specific matches a query.
* E.g., it puts together the home page when no home.php file exists.

* @package EverBox

get_header(); ?>

<div id=”primary” class=”left-column”>
<main id=”main” class=”site-main” role=”main”>
<?php the_category( $separator, $parents, $post_id ); ?>
<?php
if(have_posts()) :
while(have_posts()) : the_post();
get_template_part( ‘content’, ” );
endwhile;
everbox_posts_pagination();
else:
get_template_part( ‘content’, ” );
endif;
?>
</main>
<!– END .site-main –>
</div>
<!– END #primary –>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

and this is the content.php (bold marked line category i have added):

<?php
/**
* @package EverBox
*/
?>

<article id=”post-<?php the_ID(); ?>” <?php post_class( ‘post-item’ ); ?> <?php the_category(“,”); ?> >
<?php if(has_post_thumbnail()) : ?>
<div class=”right”>
<div class=”post-thumbnail”>
<?php the_post_thumbnail(); ?>
</div>
<!– END .post-thumbnail –>
</div>
<!– END .right –>
<?php endif; ?>
<div class=”left”>
<?php everbox_post_category(); ?>
<h1 class=”post-title”>
<?php
printf(‘%3$s‘,
esc_url( get_permalink() ),
esc_attr( get_the_title() ),
get_the_title()
);
if(is_sticky()) {
echo ‘<span class=”sub-label”>’. __(‘Sticky’, ‘everbox’) .'</span>’;
}
?>
</h2>
<?php everbox_post_meta(); ?>
<div class=”post-excerpt”>
<?php the_excerpt(); ?>
</div>
<!– END .post-excerpt –>
</div>
<!– END .left –>
</article>
<!– END .post-item –>
