Can't get lms.quickstart.com to load
I cannot get lms.quickstart.com to load. I click on the course from my portal and the page pops up and starts to load and stops on a blank page. I've tried multiple browsers (chrome, firefox, safari), multiple computers (all macOS, both Mojave and Catalina), I've tried installing (and enabling) flash (which I can't believe in 2020 is required anywhere), I've disabled ad blockers, I've cleared the cache, I've sacrificed a chicken and spread its blood on the keyboard, nothing works. Any suggestions or help?
