FINAL FIX: WooCommerce stores enabled in TWO places!
Discovery:
- wp_options: woocommerce_flat_rate_X_settings["enabled"]
- wp_woocommerce_shipping_zone_methods: is_enabled column
- We were only updating wp_options
- WooCommerce admin reads from zone_methods table
- Checkout reads from zone_methods table too!
Solution:
✅ Update wp_options (for settings)
✅ Update zone_methods table (for WooCommerce admin & checkout)
✅ Clear all caches
✅ Update in-memory property
SQL Update:
UPDATE wp_woocommerce_shipping_zone_methods
SET is_enabled = 1/0
WHERE instance_id = X
Now both sources stay in sync:
✅ SPA reads correct state
✅ WooCommerce admin shows correct state
✅ Checkout shows correct shipping options
✅ Everything works!
This is the same pattern WooCommerce uses internally.
