Hi @digitalpractice,
Thanks for writing in.
First, please update your theme. You must update both the theme and cornerstone and not just one for compatibility.
Then create this file in your child theme
framework\views\renew\content-portfolio.php
with this content
<?php
// =============================================================================
// VIEWS/RENEW/CONTENT-PORTFOLIO.PHP
// -----------------------------------------------------------------------------
// Portfolio post output for Renew.
// =============================================================================
?>
<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<?php if ( ! x_is_portfolio_item() ) : ?>
<div class="entry-featured">
<?php x_portfolio_item_featured_content(); ?>
<div class="entry-cover">
<div class="entry-cover-content">
<span>PROJECT</span>
<h2 class="entry-title entry-title-portfolio">
<a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( sprintf( __( 'Permalink to: "%s"', '__x__' ), the_title_attribute( 'echo=0' ) ) ); ?>"><?php x_the_alternate_title(); ?></a>
</h2>
<span><?php echo get_the_date( 'd.m.y' ); ?></span>
</div>
</div>
</div>
<?php endif; ?>
<div class="entry-wrap cf">
<?php if ( is_singular() ) : ?>
<div class="entry-info">
<div class="entry-featured">
<?php x_featured_portfolio( 'cropped' ); ?>
</div>
<header class="entry-header">
<h1 class="entry-title entry-title-portfolio"><?php the_title(); ?></h1>
<?php x_renew_entry_meta(); ?>
</header>
<?php x_get_view( 'global', '_content', 'the-content' ); ?>
</div>
<div class="entry-extra">
<?php x_portfolio_item_tags(); ?>
<?php x_portfolio_item_project_link(); ?>
<?php x_portfolio_item_social(); ?>
</div>
<?php endif; ?>
</div>
</article>
Thanks!
