Full Site Link refreshes Mobile Site - Doesn't go to full site

I had everything working and all of a sudden, when I click on the Full Site link on the mobile site, it doesn't return the user to the full site. It simply redirects them back to the mobile site. So, it is an endless loop.

Ideas on what is missing? How to fix?

Anyone? Any ideas?

What is the url?

winterwebmethod.com

Use Select Markup module to switch to another (mobile/desktop) mode.

I am using the option of "Redirect to domain" rather than using the dynamically generated version using modules.
It is a custom site.
Prior to the current version of this component, everything was working fine. Then I updated the component and returning to the full site stopped working.

If you like to use hardcoded link to full version, use winterwebmethod.com/?device=desktop

Perfect!!! That is what I couldn't find elsewhere.
