Post Title in Categories

@lew1s: When I check in your category, I see that you have hidden the title with css.

.entry-title {
    display: none;
}

The best option is to copy content.php file in your child theme and edit it. So, it will be like this

<?php
/**
 * The default template for displaying content
 *
 * @package Catch Themes
 * @subpackage Catch Everest
 * @since Catch Everest 1.0
 */
?>

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

	<?php if ( is_sticky() && is_home() && ! is_paged() ) : ?>
        <div class="featured-post"><?php _e( 'Featured post', 'catcheverest' ); ?></div>
    <?php endif; ?>
    
    <?php if( has_post_thumbnail() ):?>
    	<figure class="featured-image">
        <a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( sprintf( __( 'Permalink to %s', 'catcheverest' ), the_title_attribute( 'echo=0' ) ) ); ?>">
            <?php the_post_thumbnail( 'featured' ); ?>
        </a>
        </figure>
    <?php endif; ?>
    
    <div class="entry-container">

                <div class="entry-meta">

.page .entry-header, .single .entry-header, #main-slider .entry-header { display: none; }
