Wishlist - cart popup appears with link to checkout (March 2026)
Summary
If you are seeing a cart popup when products are added to the wishlist, and it contains a 'Checkout' button, please follow the instructions in this guide to either disable the popup buttons or to disable the popup completely.
Why we currently recommend disabling it
In March 2026, Squarespace introduced a new cart confirmation popup that appears whenever a product or service is added to the cart:
This popup may cause issues for sites using an older version of our Wishlist plugin, because it contains a 'Checkout' button that allows customers to proceed directly to the Squarespace checkout, bypassing the wishlist process.
How to remove the popup
You can remove the popup completely in your cart settings. Go to Settings > Selling > Cart.
You will see options for the Add to cart confirmation. Select "Button confirmation only". The change will be saved automatically.
If you would prefer to retain the popup, but remove the buttons, add the following text to the Custom CSS panel on your website instead:
/* Fix to override Mini Cart (2026) */
.commerce-mini-cart-dialog .commerce-mini-cart-action-buttons {
display: none !important;
}
.commerce-mini-cart-header-title > span {
font-size: 0;
}
.commerce-mini-cart-header-title > span::before {
content: "Added";
font-size: 18px;
}
After saving the changes, the popup should appear without the buttons.
Updating the Wishlist plugin
The latest version of the Wishlist plugin has been updated for full compatibility with this new cart popup feature. If you have purchased the subscription version of the Wishlist plugin, no modifications are necessary; the messages and buttons will automatically be customised to match your Wishlist configuration.
If you purchased the Wishlist plugin as a one-time purchase, you can purchase a compatibility update using this link: Wishlist upgrade.
