Force HTTPS on WordPress websites at Hostinger when your WordPress site fails to load over HTTPS, or looks distorted when accessed over HTTPS. Install an SSL certificate, update the WordPress Address and Site Address URLs to HTTPS, and fix any mixed content.

Scroll down and save the changes: your website will load now with HTTPS.
Step 3 (Optional) — Check for mixed content
