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. It is similar to the "purge article" feature on a Wiki. Sometimes, when changes are made to the website, they do not register immediately due to caching. A hard refresh will usually fix this, though occasionally completely clearing the cache is necessary.
