Browsers store website files (cache) and small data files (cookies) to load pages faster and remember your preferences. Sometimes this stored data causes problems: websites look broken, show old versions or have login issues. Clearing cache and cookies often fixes these problems quickly.

To reload a single page without using cached files, try a hard refresh: Ctrl + F5 or Ctrl + Shift + R on Windows, Cmd + Shift + R on Mac.
