Installing WooCommere to a site using the Sage theme causes shop pages to have duplicate content.
To resolve this, create several new files, header-shop.php, footer-shop.php and sidebar-shop.php.
This will remove both instances of the element.
You can then edit files with custom content to add required elements (e.g titles, breadcrumbs).
Example files below.
<?php if ( is_product() ):
echo '<aside>';
dynamic_sidebar( 'sidebar-shop-product' );
echo '</aside>';
endif; ?>
<?php // this file is to stop duplicate footers - DO NOT EDIT ?>
<?php // this file is to stop duplicate headers - DO NOT EDIT ?>
<?php
if ( function_exists('yoast_breadcrumb') ) {
yoast_breadcrumb('
<p id="breadcrumbs">','</p>'
);
}
?>
