Due to frequent updates to the web site, files stored by your browser can become out of date in just a few days. If something on the website just doesn't look right, go to the page with the issue and try pressing the F5 key on your PC's keyboard. This will refresh the files stored by your browser and likely correct the issue.
If this doesn't correct the issue, please feel free to respond to this thread with some details like, which page and what's not displaying correctly and what browser and version are you running. I'll do what I can to help.
