Describe the bug
A clear and concise description of what what you were trying to accomplish and what went wrong. Vague statements like X does not work are not helpful. Imagine if one of your students sent you an email that said, "My program doesn't work, whats wrong with it?" Could you help them with only that to go on?

Checkpoints 2.10.1 and 2.11.1 read:

"There was once a (temporary) Runestone exercise here, which would only render in HTML output, and never in static output forms. That (temporary) device is no longer supported as of 2025-11-04, since the exercise should now be authored in supported PreTeXt syntax. You might alert the author to this situation."

Javascript Errors
Many many errors can be quickly diagnosed from the Javascript Console error log. On Chrome this is View --> Developer --> Javascript Console, on Safari ⌥⌘i or Develop --> Show Web Inspector on Firefox Tools --> Web Developer --> Toggle Tools

Start by inspecting checkpoints 2.10.1 and 2.11.1 on the linked published page and identify their source content. Compare HTML rendering with the static output forms and update the exercise authoring to supported PreTeXt syntax. Done means both checkpoints render correctly in every supported output form.
