This takes care of a majority of problems.
Check your Internet connection.
We recommend that you have a reasonably fast connection to the internet. Any broadband connection, like DSL or cable, should be sufficient.
If you are at work or school or using a shared wireless network, there may be a firewall or proxy that is interfering with your connection to Codecademy. You can read more about that here.
Check your web browser.
- Codecademy works best on an up-to-date browser. Please use http://browsehappy.com/ to improve your experience. We recommend Google Chrome or Mozilla Firefox. Trying your exercise in a different browser is a good troubleshooting strategy.
- Check that all of your plugins are up-to-date too. Chrome, Firefox and Safari users can use this site to check the status of their plugins. You don’t need to have Flash installed to use Codecademy.
- Check your browser’s extensions. Some extensions, like ad blockers and pop-up blockers, can affect your activities on Codecademy. Try disabling them one at a time. Once you find out which one is interfering, then you may be able to configure it to ignore Codecademy.
- Clear your browser’s cache and reload the web page. Instructions for clearing your cache: Chrome / Firefox
Check your zoom level. If you have zoomed in or out on your browser, then you may see glitches in some exercises. To get back to 100%, press
- Tablets and mobile phones are not fully supported. We recommend using a laptop or a desktop.
