I had already done that, and just heard their reply. I didn’t have the ‘update’ button checked in Genesis in my dashboard, and therefore was not aware that this theme needed updating before I updated to WP 4.7. 4.7 needs 2.4.2 version of Genesis to work properly. I checked the button, got the update, all is well. Sure wish I could have found this very simple info somewhere hours and hours ago. Thanks for your help. Hopefully this post can help someone else in future.
