It may be a browser caching issue and remedied as Dave suggested, however if that didn't work, it may also be that your hosting provider has a caching solution turned on for your server. If clearing your browser's cache on Safari or Chrome, as Dave suggested, does not work for some reason, try calling your hosting provider or checking your cPanel to clear your servers cache. Are you using Wordpress or another CMS? If you have a caching plugin activated, check the cache settings on that plugin as well. And clear the cache on the plugin while your there.
Hopefully I could be of some help. Ping me if you have any other questions.
