How do I Have a contributor or author post content ? Not working…

Hi Alanna first of all lets clear few things out you don’t want to set up a user account and send them password for this you can open registrations to your website from dashboard>>settings>>anyone can register(and set the default role as subscriber which you can turn to author or contributor at any time later) this will automate the profile creating process for you and passwords will be send through emails,now the thing about author and contributors
Author=>anyone who has rights to create as well as publish their on posts on your site
Contributor=>anyone who can write posts for your site but cannot publish it by himself/herself.(in this case the post is set to be reviewed by admin and only he/she can publish or discard it accordingly thus you can move it to any suitable category you want before publishing
hope i got your doubts cleared 🙂

Hello Alanna !
At the moment, in the latest version of DW Focus theme, we have put the box of author info section on the left-hand side.
In the latest version of the DW Focus theme, we also support a co – authors plugin named co-authors plus, please try it out here.
In case this solution is not helpful for you, please follow guideline below:
If you want to display the Author info like our demo, you can do as the following: 
1. Please find here for the document guide on how to create a Child Theme.
2. Copy / paste the content-single.php file into child theme.
3. Open the content-single.php file. remove all the code then add the new following code:

       <?php
/*
* The template for displaying content on the search page.
*/
?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<header class="entry-header">
<h1 class="entry-title"><?php the_title(); ?></h1>
<div class="entry-meta">
<?php dw_focus_posted_on(); ?>
</div><!-- .entry-meta -->
</header><!-- .entry-header -->
<?php if( has_post_thumbnail() && ! has_post_format('video') && ! has_post_format('audio') && ! has_post_format('gallery') ) : ?>
<div class="entry-thumbnail">
<?php the_post_thumbnail(''); ?>
</div>
<?php endif; ?>
<div class="entry-content">
<?php the_content(); ?>
<?php wp_link_pages( array( 'before' => '<div class="page-links">' . __( 'Pages:', 'dw_focus' ), 'after' => '</div>' ) ); ?>
</div><!-- .entry-content -->
<?php dw_focus_post_actions(); ?>
<footer class="entry-meta entry-meta-bottom">
<?php if ( get_the_author_meta( 'description' ) ) : ?>
<div class="author-info">
<div class="author-avatar">
<?php echo get_avatar( get_the_author_meta( 'user_email' ), 90 ); ?>
</div><!-- .author-avatar -->
<div class="author-description">

<h2><a href="<?php echo esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ); ?>" rel="author"><?php echo get_the_author(); ?></a></h2>
<p class="description"><?php the_author_meta( 'description' ); ?></p>
</div><!-- .author-description -->
</div><!-- .author-info -->
<?php endif; ?>
</footer>
</article><!-- #post-<?php the_ID(); ?> -->

Notice: To change the author info, you can log in to Dashboard > User, find the Contact info section.
See the screenshot: 
–  To remove the author info section appears on the left-hand side, you can do as the following: 
1. Install the Jetpack by WordPress.com plugin.
2. Setting Jetpack then enable the Custom CSS feature.
3. Move through Appearance > Editor Css, add the following code:

       .entry-action .co-author {
    display: none;
}

Hope this helps !
