Are you by any chance using Edge, IE, or Safari as your browser? Free Code Camp has been updated to use newer technologies. It makes the application much faster and it means that we can go much longer without having to do a huge migration like the recent one. However, Edge, Internet Explorer, and Safari are very bad about choosing not to adhere to standards and support new functionality in JS and CSS. Right now, that means that these browsers exhibit lots of unexpected behavior. If you become a web developer you will come to hate these browsers with every fiber of your being.
I actually use Opera right now. I already hate those browsers don’t worry lmao. I’ll try Firefox or Chrome for this set of challenges and see if it works, thanks!
So it seems that the technology that is being used doesn’t work in Edge, IE, Safari and Opera… maybe the lesson that we’ve learnt is to avoid using a tech that only works only in one browser ?
