By default, WooCommerce blocks non-admin users from entering WP Admin, or seeing the WP Admin bar. These areas are usually not relevant to customers and are therefore hidden.

To disable this restriction, and re-enable the admin bar for all users, a small snippet can be added to your theme functions.php file.
If you only want to allow admin access you only need to add the first line.
/* Code goes in theme functions.php */ add_filter( 'woocommerce_prevent_admin_access', '__return_false' ); add_filter( 'woocommerce_disable_admin_bar', '__return_false' );
