Sometimes a problem can stem from out-of-date files in the browser cache. You can solve these by clearing it out.
- Exit out of any tab that has the trouble website open.
- In Chrome, hit "ctrl + shift + delete". This will open the Clear browsing data.
- in the dropdown select "All time" then Select "Cookies and other site and plugin data" and "Cached images and files". You can also choose to clear other histories under the "Advanced" tab, but these two are the important options.
- Click "Clear data" and reopen the website that was giving you problems.
