Overview of the issue
When using the Blocksy theme and WPML, the breadcrumb feature on individual product pages does not display the Shop page step for translated products.
Workaround
Please, make sure of having a full backup of your site before proceeding.
- Open …/wp-content/themes/blocksy/inc/components/breadcrumbs.php file.
- Look for line 416.
- Comment out this line:
/* && strstr($permalinks['product_base'], '/' . $shop_page->post_name)*/
