The only part I wanted to add is that I received an email notification for my customers theme on October 10th I downloaded the update and installed it for my customer and shortly thereafter the problem started. In my case I had done some customizations in Enfold Child but not only were the customizations removed all CSS was removed. I cannot use unfold child at all for my customer and they are complaining that their website looks different now. My observation is that you cannot use Enfold child with this newest updated version of Enfold.

My customer’s website is having the same issue. It has the latest version of Enfold Parent theme. I made a couple edits per their request and Enfold Child stripped away all CSS.
