Has anyone found a solution to the problem? I just started getting this message as well. It first happened around the time I was completing the Arrays portion of PHP. I asked on the Q&A forum and was told to try going back a page using the bottom left table of contents and then returning to the page that I got the error message and quickly pasting my code in. It worked then, but I've gotten the same error message about 'something went wrong :(. ' and the method that worked previously isn't working now.
Update: Someone else posted a solution to this on another thread. Basically, just put in an error into your code, like a random 'else', submit it, refresh the page and put in your code (make sure to check for errors in your code before you submit it) and then try submitting it again. This worked for me. I realized I had an extra '=' in two parts of my code, which was prompting the weird 'something went wrong' message.
2nd Update: Actually I keep getting this error message too. I thought I was done with it, but it keeps showing up every few pages. Perhaps it's a problem with the Codecademy website or we're all making the same type of mistake in our code?
