Content in displayBeforeFooter not displayed in new child theme?

[tknezek]

I'm using Prestashop 8, Classic Theme, and I just created a child theme for it, because I wanted to fine tune the page layout some. That part of the child theme process worked perfectly, but somehow the module I had displayed with the displayBeforeFooter hook (HTML Box) has disappeared?

I had an iFrame of my phpList newsletter signup form displayed with the HTML Box module. All of the settings are still exactly as I left them in the back room configuration. But the iframe is not showing anymore. I've cleared my browser cache and reloaded the page, and nothing.

I'm completely at a loss. If my settings haven't changed, and my child theme is working fine otherwise, how did that one module just stop working?

Maybe a JS issue ?  if so, try to put the JS folder of your parent theme to the child theme.
