How to fix cms version on BigCommerce
Identify your ecommerce platform and CMS version, then ensure it is always kept up to date to protect your store from security vulnerabilities and avoid loss of vendor support.
Steps for BigCommerce
- BigCommerce is a SaaS platform — core platform updates are applied automatically by BigCommerce.
- Log in to BigCommerce Admin → Storefront → Themes Marketplace: if your active theme has an update, you will see a notification — click 'Update & Preview' to review changes before publishing.
- Go to BigCommerce Admin → Apps → My Apps: review all installed apps for active maintenance status and remove deprecated ones.
- Check BigCommerce's release notes (via the BigCommerce Community or changelog) to understand what has changed and if any theme customizations need adjustments after platform updates.
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detect which platform or version your store is running, it usually means the information is hidden (which can be good), outdated, or the platform is self-hosted and unpatched.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Running an outdated or unknown CMS version is one of the leading causes of store hacks, data breaches, and payment fraud — all of which can result in lost customer trust, fines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.
