The lesson is not playing

If your code won’t run or you encounter a sync error, TypeError, or other error message issues, follow these troubleshooting steps:


  • Double check your code
    • Syntax errors, infinite loops, and other issues can cause unwanted behavior in our editor.

  • Use Incognito Mode
    • Open our platform in a private/incognito window. Some browser extensions interfere with functionality, so this helps minimize issues.


  • Try a Different Browser
    • Our platform works best on Chromium-based browsers (such as Chrome and Edge). While Safari and Firefox may work for some, they can cause compatibility issues.

  • Restart Your Browser
    • Close all browser windows completely, then reopen and try again.

  • Clear Your Cache
    • Cached files can sometimes cause errors. Clear your browser cache and refresh the page.

  • Restart Your Device
    • A full device restart can resolve temporary system issues affecting your browser.

  • Test on Another Device or Network
    • If possible, try accessing our platform from another device or a different internet network. In rare cases, network restrictions can cause errors.
