How to fix cms version on PrestaShop

Steps for PrestaShop

1. Log in to PrestaShop Admin → Dashboard: look for the update notification widget that shows your current version vs. the latest available.
2. Use the official '1-Click Upgrade' module (autoupgrade) — install it from PrestaShop Addons Marketplace if not already installed, then go to Modules → 1-Click Upgrade and run the upgrade wizard.
3. Always back up your database and files before upgrading — the module prompts you to do this.
4. After upgrading, go to Advanced Parameters → Information to confirm the new version is active and check for any module compatibility warnings.

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detect which platform or version your store is running, it usually means the information is hidden (which can be good), outdated, or the platform is self-hosted and unpatched.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Running an outdated or unknown CMS version is one of the leading causes of store hacks, data breaches, and payment fraud — all of which can result in lost customer trust, fines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.
