I have built tons and tons of sites with Muse over the years, and I have recently updated to Muse 2015. Now most, if not all of the widgets from the previously built sites, do not work when published to the web. In particular "Menu" widgets. I even tried using a menu widget directly from the Muse 2015 library, and it does not work either.
Oh, and by the meaning of "not working", you are unable to change tabs.

Any thoughts everyone??????
I'm not seeing any issues with the link you provided. Everything seems to be working correctly. One thing to remember is that the first time you publish a site after updating Muse is that occasionally you may have to upload the entire site not just changed files the first time you make changes.
