Thanks for your quick response!
I already have a page with the shortcode. That page is where the user logs in and the log off link works fine. However, once the user has accessed the protected area, I needed to add the login shortcode to a text widget to allow the user to log off while in that area. That is where the ‘logoff’ is failing to work.
If you register a new user and then login, it will take you to a page that has the widget on the right where you should be able to log off.
