CSS CSS Foundations Selectors Review of CSS Combinators

Every time I take this quiz, when I get to the "open space" question (about the adjacent sibling selector) and I fill in "+" (or anything else for that matter), I get this error screen. I had to skip this quiz for that reason.

It appears you've found a bug. You should contact the support.

I don't know if this will help support track down the problem but it seems to go through ok if it's the last question. I get the overlay window and it lets me click through to next lesson.

Are you talking about this question?

The adjacent sibling selector uses a _____________ as its combinator.

I just passed with a + sign.

I tried it, and the question gets stuck, it doesn't proceed to the next question, but it accepts the answer.

It did work with the + sign on my numpad but not with the + sign on my normal keyboard. But then it was only possible to finish the quiz when this was the last question. Same problem with the next quiz about pseudo-classes by the way...
