Same deal with me — https://www.timporter.com/seconddraft. All worked fine on last post two weeks ago. Today, Visual tab was grayed out and when clicked upon produced only a blank box. Text tab works and site publishes fine.
I’ve added no theme (Photocrati) updates or plug-ins between posts. Today, I upgraded to 3.7.1 but the issue continues.
All help appreciated.
Tim
