Can't submit answers to problems

I was wondering why I suddenly am unable to submit responses to current nor past practice problems/homework assignments, as every time I do the output is, “Something went wrong. Please get in touch, or try again.” I suspect it might have to do with the fact that the website was down for maintenance recently, so I was wondering if this is a me problem, or a website problem.

I would like to second this problem. And google searches do not seem to bring any fixes. A prompt reply is desired as a I have an assignment due today…

I just checked it again and it seems to be working now.
