Don’t show the weight

Hello Barbara,
The only way to do this in the free version is either to remove this line in the invoice template (create a custom template):

<?php if( !empty( $item['weight'] ) ) : ?><dt class="weight"><?php _e( 'Weight:', 'wpo_wcpdf' ); ?></dt><dd class="weight"><?php echo $item['weight']; ?><?php echo get_option('woocommerce_weight_unit'); ?></dd><?php endif; ?>

Or hide it with CSS:

.meta .weight { display: none; }

In the Premium templates extension you can do this with a checkbox in the settings.

Let me know if you have any other questions!
