Periodically, it's a good idea to manually clear the cache from your website browser. Cached pages are simply stored versions of web pages that you visit. Storing a copy helps the page load more quickly the next time you visit the page. The downside to always loading cached pages is that if the web page gets changed or updated, your browser might still be loading the old (cached) version. This can lead to a variety of errors or even a non-responsive site.
You can solve this issue by either doing a hard refresh or clearing your browser's cache.
