Troubleshooting Command Center: Blank Screen
If you visit a website frequently, your web browser stores elements of the web page in a cache so that they do not have to be downloaded again each time you visit, making your browsing faster. In some cases, when the website is changed, you may not be able to view the changes because you are actually viewing the cache. There are two ways to solve this problem: a hard refresh, which bypasses the cache and loads the actual page as it is stored on the server and clearing your cache, which is something you should do periodically anyway.
A hard refresh is a way of clearing the browser’s cache for a specific page, to force it to load the most recent version of a page. Sometimes, when changes are made to the website, they don’t register immediately due to caching. A hard refresh will usually fix this, though occasionally completely clearing the cache is necessary.
How to do a hard refresh on various browsers?
Chrome:
