If the pages you are viewing on the website seem out of date, your web browser may not be updating them. It is probably showing a version of the page cached in the browser's cache.
The website is changed throughout the day, so you need to set your browser to look for the latest pages on the site. Otherwise your browser will look at the last version you viewed, which is saved to the browser's cache. The browser does this to speed up the time it takes to retrieve the requested page.
To override this and download the most recent page, try clearing out your cache by pressing the browsers 'Refresh' button to ensure the most up-to-date pages are viewed. You can set your browser to do this automatically by setting the browser options to check for a new page every time you visit a site:
Internet Explorer browser family:
Choose Tools/Internet Options/General
Click on the 'settings' button in Temporary Internet files and choose the option 'Check for new page every visit to page.'
Firefox browser family:
Click on the 'Clear' button
Click on the 'Clear Browsing' button
Some Internet Service Providers and some Local networks have caches set up to save on bandwidth. These caches may be set to refresh every day or every few days rather than every time a user accesses a site.
