I create Step 1 of a course (title, short description, image) and click next. The next screen is completely blank. I look at a preview of the course (in draft) and there isn't any course description. I tried editing the course and only get a blank screen with three tabs; Course Setup (blank), Units, and Students. I can add multiple units, but cannot edit the basic course information. I am using WP 4.7.1 and a 3rd party theme.
