How do I use a shortcode in an Upfront site?

I have a plugin that can work via shortcode in any post or page. I had it working, then the license got wonky so I wound up re-installing it and now I can only get it to work as a widget. The shortcode isn't cooperating. The widget version is quite unsatisfactory. How do I get the shortcode to work again? I've tried the </>, the text box, and the text widget.


Thank you. :slight_smile:
