How to fix ssl expiry on PrestaShop

Steps for PrestaShop

1. SSL is managed at the server/hosting level, not inside PrestaShop.
2. Log in to cPanel or your hosting dashboard and enable AutoSSL or Let's Encrypt for your domain.
3. Inside PrestaShop admin: go to Shop Parameters → General and enable 'SSL' and 'Enable SSL on all pages'.
4. On self-hosted servers, use Certbot: `sudo certbot renew --dry-run` and verify the cron or systemd timer is active.

What is ssl expiry?

A TLS (SSL) certificate is the digital credential that puts the padlock in your visitors' browser bar and enables the secure "https://" connection to your store. Every certificate has an expiry date — typically 90 days (Let's Encrypt) or 1–2 years (paid CAs). When it expires, browsers immediately block visitors with a full-screen "Your connection is not private" warning, and the padlock disappears. Auto-renewal is a process (a scheduled script or a hosting feature) that requests a fresh certificate a few weeks before the old one expires, so the swap happens invisibly to shoppers.

An expired certificate is an emergency: every visitor sees a hard browser warning and most will leave instantly, causing an immediate and total loss of sales. Google also uses HTTPS as a ranking signal, so a lapsed certificate can drop your organic rankings. Payment processors and card networks require an active TLS certificate — an expired cert can cause checkout failures and put you in breach of PCI-DSS compliance. Setting up auto-renewal costs nothing and takes minutes; ignoring it risks hours or days of complete store downtime.
