How to switch a Moodle website to https?

1. Update the config.php file in the Moodle root directory to include the following lines:

$CFG->wwwroot = 'https://example.com';
$CFG->httpswwwroot = 'https://example.com';
$CFG->httpsadmin = true;

2. Replace example.com with your actual domain name.
   • You may also need to update the httpswwwroot and httpsadmin parameters if you use a different domain name for your Moodle administration area.
3. Replace all occurrences of http:// with https:// in your Moodle templates, CSS files, and other static files.
   • You can manually replace the http:// prefix or use a search and replace tool to ensure all links utilize HTTPS.
