The current website was customised according to the advice in https://premium.wpmudev.org/blog/twenty-seventeen-wordpress-theme/. I applied home page sections and moved the Blog to its own page.
These screenshots show how the child theme appears using the Live Preview button from the Appearance sub-menu:
- the home page sections ‘Services’ and ‘Contact’ (and their featured images, are not showing)
- the Blog appears on the home page (it should not)
There may be other issues.
