When you visit websites, copies of the web pages are “cached”, or saved, to your local computer. Then the next time you visit the same web page, the cached page is usually displayed, instead of retrieving the page from the website again. This is done for speed. However, when our website changes, especially when changes to navigation or functionality are made, you may not be looking at current content and features from our website. And sometimes it may seem like the website isn’t working correctly as a result.
When the above happens, or simply on a regular basis, it’s good to clear your web browser cache and cookies.
