Save not working

None of my projects will save!

I have noticed that none of my projects will save. It won't work for Javascript, HTML/CSS, or SQL. I am referring to the Save button right by the spin-off button, and restart/reload, where used. Any time I try to save my new program, this message pops up:

Error

Error saving your creation to the server. Please try again!

I have tried to reload the page, I have tried to save it multiple times in a row, but nothing seems to work.

To my knowledge, this is a problem affecting multiple programmers.

I suspect Khan Academy may be updating, as once I made a program and a little scrollbar showed up. It listed all the possible functions I could be typing, but I'm not sure if this is new, or even part of the problem.

If anyone could help or provide details, I would appreciate it.
