Sometimes older versions of pages are cached in your browser and can provide challenges when trying to navigate and/or log in. A good practice is to clear your cached files and cookies. Below are some instructions on how to do so in Chrome.
While in Chrome, click on the 3 horizontal lines towards the top right of the browser. Once you have done that, click on "More Tools" then click on "Clear Browsing Data".
From here, select "the beginning of time" next to "Obliterate the following items from". After you have done that, select just "Cookies and other site and plug-in data" and "Cached images and files". Next, click on "Clear browsing data".
