Content Blocking

Is there content "missing" from view within your Blackboard Learn course site?


Internet browsers are now automatically blocking Mixed Active Content. Mixed Active Content linked within course sites can include campus pack blogs or wikis, iTunesU, Flash animations and/or streaming of audio or video. This is a security enhancement that prevents Active Content delivered through an unsecure (HTTP) connection from displaying on a secure (HTTPS) website. Malicious Active Content has the potential to change a secure page, allowing an attacker to capture sensitive information sent to and from a user’s computer. Blocking active content prevents this type of attack.

To temporarily allow mixed content during the time spent within your Blackboard Learn course site, you would need to explicitly allow the content to load, otherwise you would get a blank area where you expect content to appear. Know that you can permanently disable the blocking of mixed content, however, this decision is up to you as it may put your computer at risk. Please find your preferred browser below and follow the steps to change the settings:
