This is generally one of two things: 1) You have an old version of the page loaded on your browser. Your browser will cache (store) parts of a website so that it will load faster. To flush this cache, you can do a "hard refresh," which on Windows is usually ctrl+f5 (command + R on Mac), or you can delete your browser cache/cookies in the browser's settings. Restarting your browser and computer will often solve a cache issue. 2) You might be using a different Internet browser to view the web. (See next question)
