Learnr tutorial shows only output, not input code box

We deploy learnr tutorials via this package to our intro to econometrics course: GitHub - ScPoEcon/ScPoEconometrics: Undergraduate textbook for Econometrics with R

if you install it with

install_github(repo = "ScPoEcon/ScPoEconometrics")

you can run an associated tutorial with runTutorial('chapter2'). This works perfectly for the majority of our students. One student, however, sees a browser with only the printed output of the last command instead of the actual codebox where they are supposed to enter code into. has anyone ever experienced this?

Strange, indeed! Can you give some detail about the setup of that computer? Is the student using the same browser as everyone else? Are there any extensions active, etc?

that's what I thought! here is her sessionInfo:

then she launches and sees this in her console (browser is as described - no code box!)

Listening on

That's really strange. Since it's happening in the IDE browser, and doesn't seem to happen with any other machines, you might want to move this into #rstudio-ide (though, of course, your thread's fine staying here). Just trying to think of how to get the right eyes on your issue!

thanks! I think I changed the labels on the question - anything else I need to do?
