Strange. I don't get any error you speak of when taking the test. It just gets accepted. I'm singed in so try signing first and then take the test. Either way, its still annoying maybe the website is still a work in progress who knows. You can also contact the author with the email provided in the about page.

I got the same problem. The answer is exactly what I typed. Developer needs to fix it. It should do what it says whether the user is logged in or not.

print("Line #1") print("Line #2")

Same. I don't think any of the tests work properly.
