Error: “Unable to load calendar data”

Try disabling other plugins to see what might be conflicting with it.

Particularly “Siteground Optimizer” and “Signup Form Widget” which are both throwing errors on your events page in the console.

Can you share the .ics link you are using?

It looks like your calendar may not be set to “public”

Got it. It’s not the .ics but rather your security plugin, or theme is blocking unauthenticated REST requests. The endpoint is returning: {"code":"rest_api_authentication_required","message":"The REST API has been restricted to authenticated users.","data":{"status":401}}

You might check your settings for something like “Disable REST API” or the like, and see if you can whitelist /wp-json/hycal/*

Or if it’s hard-coded, you can try something like the following (untested, going from memory):

add_filter('rest_authentication_errors', function($result){
  if (! empty($result)) return $result;
  $uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';
  if (strpos($uri, '/wp-json/hycal/') !== false) return null;
  return $result;
});
