This is a known issue related to the Internet Explorer (IE) web browser. IE sometimes has trouble understanding the instructions sent when you preview or click on certain links. When IE can't understand the preview or link information, it will display an error message instead of displaying the content you requested.
To remedy this problem, we recommend using Mozilla Firefox as your computer's default browser. When you preview or click links to sites outside of SiteBuilder, the expected new window will open in Firefox instead of IE, thus avoiding the IE-specific error.
You can download Firefox for free.
To set Firefox as your default browser:You should no longer have issues with previews or links.
