This may be due to additional security that has been added to the website. At this time, the internet is moving towards enabling security on all sites and we have implemented SSL certificates in order to keep up with this development. SSL (Secure Sockets Layer) certificates are currently being rolled out to all front end websites managed with School Website. These SSL certificates improve the security of all  sites. They also include  Web Application Firewall (WAF) which adds new protections for your site, including enhanced protection from XSS and SQL injection attacks, among many others.

Additionally, SSL encourages search engines (like Google) to list your school’s site higher in relevant search results. It also indicates to your website’s visitors that your website and their internet browser are communicating with an encrypted link for increased safety and security. You and your site’s visitors do not need to take any extra actions to benefit from this update.

The SSL certificate will appear in the internet browser's address bar, just before your site’s URL. You may also notice a small padlock icon indicating this extra privacy.

To avoid issues with secure sites and to display resources placed on a secure page, the embed or iframe content should also be secure or the browser will have errors displaying the resource. At this time, you must obtain a secure link for the embed or iframe, or add the s to http in the resource (which will work depending on how the embed is setup by the provider).
