I'm in the middle of this unit (on Neighbourhood Guides: Grid) and suddenly codecademy's website just won't load my new code at all. The browser tab just does that little circle that means it's sending forever and ever but the preview never updates and I can't submit (again, sending forever). Has anyone else had this problem? I'm using firefox 43.0.3. Everything was working fine until this lesson.
Oh wait. I might have updated my Java. Would that be a problem? How do I fix it?
