Reply To: Enable text at the top of a portfolio page

You can copy the content from the new version of the portfolio template near the top of the file and paste it to your current version (if you’re not using the latest) –

// Adds Page Title
add_action( 'genesis_before_content', 'genesis_do_post_title' );

//Adds Page Content
add_action( 'genesis_before_loop', 'ally_do_portfolio_content' );
function ally_do_portfolio_content() {
    echo '<div class="entry-content entry-portfolio" itemprop="text">' . get_post()->post_content . '</div>';
}
