Thank you for your response. When I pressed the Auto configure button, which according to the help file should have loaded some kind of live preview, what exactly got changed and in what files? I have a custom theme and after the site broke I then read that I needed a child theme? In any case, I did duplicate the the page.php and rename it to product-adder.php etc after the site broke but it had no effect and the site is still down. I would like to know what code to remove or modify to put it back to how it was before.
