Question

functions in function.php Wordpress
In function.php on Wordpress added function to insert product description in Woocommerce by short code
<code>
function woo_description() {
global $product;
echo $product->get_description();
}
add_shortcode( 'woo_desc', 'woo_description' );
code>
Shortcode [woo_desc] added to product card template in Woocommerce.
At some point when updating the theme or plugins, the product card template began to give a "Server Error 500" error when trying to make any changes. Changes are not saved. When you remove the shortcode from the template, the error disappears and you can make changes to the template.
