How to fix ssl cert expiring soon on WooCommerce

Steps for WooCommerce

1. WooCommerce itself does not manage SSL — the certificate is handled by your web host or server.
2. Log in to your hosting control panel (cPanel, Plesk, Kinsta, SiteGround, WP Engine, etc.) and go to the SSL/TLS section.
3. If using a host with Let's Encrypt integration (most shared hosts): find 'Let's Encrypt' or 'SSL/TLS Status', click 'Renew' or confirm auto-renewal is toggled on for your domain.
4. If using a paid certificate: download the renewed certificate files from your CA and upload them under SSL/TLS → 'Install and Manage SSL for your site'.
5. After renewal, install the WordPress plugin 'Really Simple SSL' (free) to verify your entire site runs over HTTPS and to force redirects — it will flag any mixed-content issues introduced by the renewal.
6. In WordPress Admin → Settings → General, confirm both 'WordPress Address (URL)' and 'Site Address (URL)' start with https://.

What is ssl cert expiring soon?

An SSL/TLS certificate is the digital credential that proves your website is who it says it is and encrypts the connection between your store and your customers' browsers — it's what puts the padlock icon and "https://" in the address bar. Every certificate has an expiry date, after which browsers will show a full-screen red warning ("Your connection is not private") to anyone who tries to visit your site. Renewing means getting a fresh certificate installed before the old one runs out. Most certificates last 90 days to 1 year, and renewal should be started at least 30 days before expiry to allow time for any issues.

When your certificate expires, every major browser — Chrome, Safari, Firefox, Edge — will block visitors with a hard security warning before they even see your store. This instantly destroys trust and conversions: most shoppers will leave and never return. Google also uses HTTPS as a ranking signal, so an expired certificate can hurt your organic search visibility. If you collect any customer data (names, emails, payment info), operating without a valid certificate exposes that data to interception and puts you at legal risk under privacy regulations such as GDPR and PCI-DSS. Even a single day of expiry can cause lasting damage to your brand reputation.
