# Duplicate orders or order synchronization issues after upgrading to MultiVendorX 5.0.0. How can I fix this?

If you've recently upgraded to **MultiVendorX 5.0.0** and are experiencing issues such as:

- Duplicate orders being created
- Orders appearing multiple times
- Order synchronization problems between WooCommerce and MultiVendorX

the first thing to check is whether **High-Performance Order Storage (HPOS)** is enabled in your WooCommerce settings.

### Resolution

1. Go to **WooCommerce → Settings → Advanced → Features**.
2. Verify that **High-Performance Order Storage (HPOS)** is enabled.
3. If HPOS is disabled, enable it and save your changes.
4. Once enabled, check whether the order-related issue has been resolved.

In many cases, enabling HPOS resolves duplicate order and synchronization issues after upgrading to MultiVendorX 5.0.0.

If the problem persists even after enabling HPOS, please reach out to our support team with the relevant details, and we'll be happy to assist you further.
