CoursePress Pro Theme Not Loading for front end customization

Hi, I am having a bit of a problem. When I go to customize my coursepress pro theme from the dashboard, or from appearance themes courspress customize, it does not load. It comes up with a blank page. What is happening. It worked previously. Please let me know what I can do to fix this. Thank you for all your help and support in advance! :slight_smile:
