SSL errors explained

What this solves

Your browser shows an SSL error (e.g. “Not secure,” “Certificate invalid,” or “Mixed content”). This guide explains common causes and fixes.

Certificate invalid / not trusted

Often: certificate expired, wrong domain, or self-signed. Install or renew a valid cert (e.g. Let’s Encrypt in cPanel). Ensure the certificate covers the domain you’re visiting (including www if used).

Mixed content

The page is HTTPS but loads images or scripts over HTTP. Browsers block or warn. Fix: load all resources over HTTPS. In WordPress, use a plugin or search-replace to change http:// to https:// in the database (after backing up).

Wrong certificate

You see a certificate for another domain. The server may be serving the wrong vhost. Check server config or contact support so the correct certificate is used for your domain.

When to contact support

If you’ve installed a valid cert but the error persists, we can check the server configuration.
