Works in Live App Connect but no on Website

I’ve created a Bootstrap 5 table to show info from a database.
It works perfectly inside of Wappler when using the “App Connect Mode” or “Toggle Preview Mode.”
All my database data shows up in nice rows, etc.

But when I upload it all to the live site the table has none of the Database info. It just looks empty.

Any ideas on why this might be?

(Wappler 4.0.1. PHP 7, MariaDB, Apache)
