I am unable to save elements in CoursePress Pro

I am unable to save elements in CoursePress Pro on pages within units. When I add an element and press preview, nothing happens. If I press save it looks like it is working and then the page refreshes and deletes whatever I have added. Also, I cannot see the visual side of of the back-end. So there is no way for me to add pages to my course.
