Web page configuration settings do not take effect.
This is a common caching problem found most often with Microsoft Internet Explorer. A good fix is to tell your browser to check for new versions of a web page with every visit to the page. Also make sure you are clicking on "ok" and "apply settings" after you are done changing a configuration in the web page
configuration manager.
To change your Internet Explorer settings:
Click on Tools > Internet Options >
Locate "Temporary Internet Files" and click "Settings"
You will see: "Check for newer versions of stored pages"
Select the radio button that says "Every visit to the page"
