404 Error - Introduction to 'For' Loops


When I hit the Save & Submit Code button, I get a 404 and the window locks up. Before that point, I can edit and write code within the online console as I see fit. This has happened when I edited code, and it's also happened when I didn't do anything to it. I am using Google Chrome.

Below is the error, found in devtools:

Failed to load [https://www.]codeacademy.com/assets/ace/worker-javascript.js resource: the server responded with a status of 404 (Not Found)

(Unfortunately, I couldn't post this with the link above as functional. Sorry!)

If you could fix this, that would be great. I'm really enjoying the class. Thanks!


This is likely the result of a known problem many users have been experiencing. It was supposedly patched. Try using a different browser, and if the error persists, report it as a bug.


I tried it in another browser - Firefox - and it stalled out before a pop up window appeared, which contained the following:

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: https://production.cdmycdn.com/assets/dist/common-db66576f48cac825e0e5cd640bbf29a3.js:1"

How do I report it as a bug? When I checked the FAQ, it suggested I go here.
