What is cache?
Browsers saves locally files that are often downloaded over and over again. Because of this, it can happen that a browser “thinks” there’s no need to go get file on the server — after all, it thinks the files haven't changed —, that is what is called cache.
In many cases this is useful and speeds up a page download time. However, it can lead to false-positives, where a browser doesn’t realise the files actually have changed. And that sometimes happens to break down the Dashboard, as new files and old files are mixed.
Here is how to clear your browser cache:

Open a new window/tab and copy and paste this URL in Chrome address bar:
chrome://settings/clearBrowserData
