#HTTPS
HTTPS is the encrypted version of HTTP that every modern website is expected to use. Articles tagged here explain how HTTPS protects visitors and what browsers do when it is missing or broken. They cover redirects from HTTP, mixed content, HSTS and moving an existing site to HTTPS. You will find step-by-step instructions for common servers, hosting panels and content management systems. Each guide also explains how to verify that the change really works. Use these articles whenever a browser shows a padlock problem or a Not Secure label.
