On occasions, websites may not behave as expected or not appear to be responding at all. To fix an issue like this, it may be that your browser requires its cache to be cleared.
What is cache?
A cache stores copies of all data that passes through the browser, like HTML pages and images, and helps display a web page. When you first visit a website, it might take time to load all of the online content, like images or videos. However, once it’s saved to the cache, your subsequent visits will load faster. Occasionally clearing your browser cache improves your speed and performance and ensures you access the latest version of a web page.
Clearing cache depends on the browser you use. Here are the links to the instructions for some of the more common browsers.
