When the website is upgraded, it sometimes needs to have a HARD REFRESH done. The following is a borrowed article* that explains how to do it. If changes made to a web application or website don’t register immediately due to caching, a hard refresh will usually fix this, though occasionally completely clearing the cache may be necessary. A hard refresh offers a quick and easy way to clear the browser’s cache for a specific page, forcing it to load the latest and greatest version of it. If you are getting error messages, this is the First Thing to Try to stop the errors.
Do the following based on your browser and setup.

- Press the Ctrl key on your keyboard while clicking the Reload button in Chrome.
- Or press Ctrl + Fn + F5 on your keyboard.
- Or open the Chrome Dev Tools by pressing Ctrl + Shift + I on your keyboard or right-click anywhere on the page and select Inspect.
