My site stopped working after switching to HTTPS

This usually happens if you enabled the Redirect from HTTP to HTTPS option, but your site doesn’t actually have an SSL certificate installed.
To fix this, add the following code to your theme’s functions.php file or use a plugin like ProFunctions:

/**
 * Disable Clearfy redirect from http to https
 */
add_filter('clearfy_redirect_from_http_to_https', '__return_false');

Once you’ve added the code, log in to your WordPress dashboard and disable the Redirect from HTTP to HTTPS option. After disabling it, you can remove the code you added.
