6.6.7 and homepage issues

So after updating last night, I have noticed that my home page for http://www.cantrellmorgan.com is showing fine on desktops, but for mobile/responsive – at least on phones all content except menu/widgets are gone?

Any suggestions?

Also I have been out of the loop since 6.6.3 until now, I know there have been changes but I have also noticed errors when I “Inspect element” in chrome. 404/400 errors (see attached).

When I upgraded from 6.6.3 manually I did reuse my child theme that was created in 6.6.3, was I not suppose to do that ?
