Squarespace Cart Changes [27 January 2021]
Squarespace upgraded a key component of the Cart page, causing unscheduled changes to the Cart page markup on all live Squarespace sites. The human-readable classes were removed and changed to auto-generated codes prefixed with underscores. These changes adversely affected all custom code on this page, including style changes and custom scripts.
Squarespace engineers successfully rolled back these changes on 29 January.
Squarespace engineers pushed out the same update on 16th March 2021. This caused the same issues for all site owners who had customised the cart in any way. Squarespace refused to roll it back this time, stating that the update was necessary and could not be avoided in the long term. In a statement after we complained about these changes, Squarespace said βPlease bear in mind that the [cart] may change [again] without notice [leading to further failures]. Product and Engineering teams are aware of the challenge this poses to usersβ¦but we donβt have a timeline for possible solutionsβ.
