Clearing the Cache of your Web Browser
Web browsers and Proxy filtering servers cache websites to allow quicker access to users. However, on occasions the new website data/code is not retrieved which can cause some display issues, faults not be resolved or other issues with the website.
Most of the time a refresh (click F5 on the keyboard) or a force refresh (Ctrl + F5 on the keyboard), can force the browser to request the latest website content resolving these issue immediately.
If you are still experiencing issues then clearing the browser cache can fully flush out any locally held website data.
