Is it possible that you’re using a computer that has already been used by someone who has completed the freeCodeCamp challenges? It sounds like the solutions have been cached in the browser storage. You should be able to fix this by clearing the application cache of your browser.
It might be possible. Am i losing recent work done on freecodecamp as well by clearing the cache?
You would lose any local solutions (which is the point) but the challenges would still be marked as completed.
There are two different types of saved progress for Free Code Camp: your profile and your browser cache.
A list of your completed challenges is saved to your account in the FCC database. You can see the list of completed challenges by looking at your public portfolio. With a growing curriculum already over 1,400 lessons and a community of millions of people, FCC does not store every solution to every challenge in its database. When you complete a challenge, there is a modal that gives you the option to download your solution. This gives you the option to save a copy of any solution that you may want to reference later. There are some challenges which are classified as projects required for certifications. Your solutions to those can be viewed on your settings page.
Your in-editor code is saved in your browser’s local storage. Recent in-progress code from the challenge editor is also saved in your local browser cache when you run tests. If you are completing lessons and do not see your recent code, then your local storage has been cleared or something is preventing FCC from writing to your browser’s storage. This could be a browser setting, a privacy extension, or a browser version incompatibility. Especially as you get to more complicated challenges that may take multiple sessions, I strongly recommend saving your in-progress work outside of the browser cache.
Cleared my browser’s cache and it’s all good now. Thank you!
