The most recent update to Coursepress Pro will not let me save any elements in the units.

I updated Coursepress Pro to Version 1.2.2.7, and now I can't save any elements in the units. When I add text boxes, video containers or anything else and then I hit save, it just disappears. When I add pages to the unit and hit save, those also disappear. I have confirmed this with several courses that I have in production on several different domains.

I can grant access to a site if you need it.
