# Why are the checkout extension buttons greyed out?

If the checkout extension buttons are greyed out in Platter+, it means that checkout extensions are not currently available for your store.

## **Why is this happening?**

Checkout extensions require **Checkout Extensibility**, which is **only available to Shopify Plus stores**. Additionally, Platter+ checkout extensions are only accessible to merchants on the **Pro plan**.

## **How to Enable Checkout Extensions**

To use checkout extensions in Platter+, you must:

1. **Be on Shopify Plus** – Checkout Extensibility is only available for Shopify Plus stores.
2. **Upgrade to the Platter+ Pro Plan** – Checkout extensions are a Pro feature.

If your store meets these requirements and the buttons are still greyed out, try refreshing your Shopify Admin or reach out to our support team for assistance.
