Up to version 12.0.742.91 of Google Chrome, the browser is known to have a problem caching old pages even after new pages have been uploaded
One possible solution to resolve this issue would be to place the following code within the head tag of your website
<meta http-equiv="pragma" content="no-cache">
You could also add the follow code to force a refresh of the current page the customer is viewing.
<meta http-equiv="refresh" content="60">
The 'content' value is in seconds so "60" is equal to 1 minute.
