Turn on SSL (HTTPS)
Free Let's Encrypt certificates that renew automatically.
Turn on SSL for your website
Your domain's nameservers must point to us first.
- In the Web tab, click your domain to edit it.
- Tick Enable SSL for this domain, then Use Let's Encrypt to obtain SSL certificate and Enable automatic HTTPS redirection.
- Click Save. The certificate details appear below the boxes when it's done.

Afterwards in WordPress
In Settings → General, make sure both addresses start with https://.
If Let's Encrypt fails
Most often the nameserver change hasn't gone through yet. Check it and try again later.
