Woocommerce Coupon Menu and Marketing Menu missing After “Coupons can now be managed from Marketing > Coupons.” [closed]
Found the solution to bring back Legacy WooCommerce->Coupon menu back. Go to your database, and go to wp_options table(check prefix of table in your wp-config.php file) and find this wc_admin_show_legacy_coupon_menu under option_name column, set its value from 0 to 1.
