A Tab on My Dashboard Does Not Display or Opens a Different Web Site

When I try to view a tab on my Dashboard:

• The tab is not opened.
• Another web site is displayed.

The tab has a Website widget that is accessing a web site that is not optimized for widget use. You must delete the tab and create the tab again.

To avoid this in the future, you must create a "test" tab and add the Website widget to ensure the web site behaves as expected before adding a Website widget to an existing tab.
