Hey @zencracker,
The Archive Subtitle is coming from _landmark-header.php and it’s located in x\framework\legacy\cranium\headers\views\integrity.
Create this directory in your child theme x-child\framework\views\integrity and copy that landmark file in that folder.
The code block responsible for the category landmark is this:
<?php elseif ( is_category() || x_is_portfolio_category() ) : ?>
<?php
$meta = x_get_taxonomy_meta();
$title = ( $meta['archive-title'] != '' ) ? $meta['archive-title'] : __( 'Category Archive', '__x__' );
$subtitle = ( $meta['archive-subtitle'] != '' ) ? $meta['archive-subtitle'] : __( "Below you'll find a list of all posts that have been categorized as ", '__x__' ) . '<strong>“' . single_cat_title( '', false ) . '”</strong>';
?>
<header class="x-header-landmark x-container max width">
<h1 class="h-landmark"><span><?php echo $title ?></span></h1>
<p class="p-landmark-sub"><span><?php echo $subtitle ?></span></p>
</header>
Just remove this line:
<p class="p-landmark-sub"><span><?php echo $subtitle ?></span></p>
