What is a "browser cache"?
Your internet browser's cache stores snapshots and images used by webpages you visit on your computer or mobile device so the pages load more quickly when you visit the page in the future.
Occasionally your cache prevents you from seeing updated content or causes functional problems when stored content conflicts with live content. You can fix many browser problems simply by clearing your cache.
How to clear your browser's cache?
Before you start, please make sure you are using the latest version of your browser.
Visit this site: http://www.refreshyourcache.com for help clearing your cache. The site contains browser-specific pages that provide instructions for clearing the cache for your browser.
When clearing your cookies and cache, please make sure that you only select cookies and cache, do not select "Form fill data" or "Passwords", as it will delete those as well.
If you use Safari, be aware everything (cookies, usernames, passwords, cache, etc) will be cleared.
