How to fix cms version on Squarespace

Steps for Squarespace

1. Squarespace is a fully hosted SaaS platform — all core updates are applied automatically.
2. Log in to Squarespace Admin → Pages or Design → Template: check if your template version has any available updates or migration notices from Squarespace (they email account owners).
3. If you are on an older Squarespace 7.0 template, consider migrating to a Squarespace 7.1 template, which receives ongoing updates and new Commerce features.
4. Go to Commerce → Extensions: review all connected extensions for active support status.

What is cms version?

Every online store runs on a content management system (CMS) or ecommerce platform — such as Shopify, WooCommerce, Magento, BigCommerce, or Wix. Each platform releases version updates that fix bugs, patch security holes, and add new features. When a security scanner cannot detect which platform or version your store is running, it usually means the information is hidden (which can be good), outdated, or the platform is self-hosted and unpatched. Keeping your CMS on a current, supported version is one of the most fundamental maintenance tasks for any online store.

Running an outdated or unknown CMS version is one of the leading causes of store hacks, data breaches, and payment fraud — all of which can result in lost customer trust, fines under regulations like GDPR and PCI-DSS, and even having your store blacklisted by Google (which directly destroys organic traffic overnight). Search engines also use site health signals — a hacked or flagged site loses rankings fast and is extremely difficult to recover. On the revenue side, a compromised checkout destroys conversions and can get your payment processor account terminated. Staying on a supported, up-to-date version means you receive security patches as soon as vulnerabilities are discovered, before attackers can exploit them.
