Highend & Woocommerce related errors

1.) I am getting the following error on all category pages:

Undefined property: stdClass::$post_name in /var/www/eheartmonitor.technology/wp-includes/template.php on line 317

2.) An error occurs when a viewer adds a Woocommerce Bundled Product or a Woocommerce Subscription Product to the cart. The item is added put the page header stretches vertically in a “broken way”.

3.) I would like to change the icon for the cart from a handbag to a cart and I cannot find the controls, or references to changing the icon in the documentation.
