I’m experiencing the same exact issue with this child theme, everything is great when viewing the customize theme section/live preview but format is a mess on the live site. Looking forward to some feedback on this!
Update:
It appears that all of the widgets and images (Except posts) are just samples so they’re removed when the Lite version is published, which likely causes the formatting issues. I inserted some random text in each section and it looks perfect. I’ve been going at this for 3 days, go figure I just needed to put my own content/images in!
