Hi,
Just wanted to point this out in case it is a bug / mis-type.
in themes/xstore/woocommerce/global/breadcrumb.php i saw the following line of code and am assuming it may be incorrect, around line 56.
<?php if( ! etheme_get_option(‘product_name_single’) && is_single() && ! is_attachment() ): ?>
<?php if( ! etheme_get_option(‘product_name_single’) && is_single() && ! is_attachment() ): ?>
