Can no longer add a non-relative URL into navigation menu
You can no longer add a non-relative URL into the navigation menu (via Course Setup > Appearance). You used to be able to do this, along with doing this ~/ (this would be useful again).
You can see it in any course, but can check this course with the URL in navigation: https://www.openlearning.com/courses/brooke-graphic-design-example/HomePage
There are many courses that have non-relative URLs already set up and they are now going to "broken" pages:
So the same issue happened to fullamark courses yesterday (10/10/18) around 4pm MYT.
Fullamark is a custom domain portal and the default page was navigated to the Announcement/Blog page.
Example of one of the courses: https://backend.fullamark.com.my/courses/BahasaInggerisSpm
Updates: Danny released the fixes at 9.40pm.
