Hi there,
Thanks so much for using Dynamico.
It seems the whole JavaScript for the Tabbed Content widget is missing. I suggest to disable the WP Super Cache plugin temporarily to see if it fixes the issue. I guess that maybe due to script minification of the caching plugin it is not properly loaded.
If it works then you have to tweak the settings of the WP Super Cache plugin so it does not break the widget.
Hope that helps.
Cheers,
Thomas
