When Icons are not showing up on your website, check the following:
Your site content might be loaded using the wrong protocol, "HTTP" instead of "HTTPS", which could happen if changes were made to your SSL settings or if it was not set up properly. You can check this by logging into the backend of your website and navigating to Settings > General and ensure you have updated the site URLs.
If you migrated your website, ensure you have cleared the Avada Caches by navigating to Avada > Options > Performance > Reset Avada Caches.
