When using the German Market Plugin, Smart Theme, and WooCommerce, the checkout form will not render properly.
In order to fix this, please disable German Market's Woo Template Override.
The URL path to the setting is
/wp-admin/admin.php?page=german-market&tab=general&sub_tab=cart_and_checkout
Prefix the above URL path to the end of your site URL, like
https://yoursite.com/wp-admin/admin.php?page=german-market&tab=general&sub_tab=cart_and_checkout
You should see a setting there called "Deaktiviert German Market Hooks" (it should be turned on).
