Troubleshooting: Browser Issues

Our platform performs best with up-to-date browsers -- out-of-date browsers can cause performance issues in our code runners and answer checking systems. 

Most issues students experience can be resolved by following the steps below:

1. Attempt a hard refresh in your browser. This clears your browser's cache and forces it to load the most recent version of that page.
   • Windows/Linux:
     • Hold down Ctrl and press F5.
   • Mac
     • hold down ⌘ Cmd and ⇧ Shift key and then press R.
2. Clear your cookies and cache with these steps
   • If the information in your browser is outdated, it can cause performance issues with a variety of platforms — clearing your cache and cookies gives your browser a fresh start.
3. Remove browser extensions with these steps
   • Browser extensions can interact with platforms and cause performance issues. If you have any trouble with this step, you can check out a quick guide here.
4. Try a different browser
   • If the issue disappears in another browser, then it may be that you need to update your first browser. Follow the steps below:
     • Update Google Chrome
     • Update Firefox
     • Update Safari
     • Update another browser
