I have this problem recurrently and it does not let me advance regularly. Does anyone know how to solve it?
As far as I know there aren’t any server outages right now. Here are some debugging tips:
- freeCodeCamp works on the current versions of Chrome, Firefox, Safari, and Edge. If you are using another browser, consider changing. If your browser needs to update, please do so.
- Make sure that extensions that block scripts (ad blockers, script blockers, some security extensions) have an exception for freecodecamp.org. They can prevent freeCodeCamp from working correctly.
- Make sure that third party cookies are allowed.
- Sign out of freeCodeCamp, then clear your browser cache, then log in again. Make sure to copy any in-progress and save it outside of freeCodeCamp before doing this.
Let us know if this helps.
