HTTP error 500 when trying to create a new course if Divi theme is active

I’m getting a HTTP error 500 when clicking on CoursePress Pro > New Course.

After running a plugin/theme conflict test I’ve found that the issue is there when having the Divi theme active on the site and other WPMU DEV plugins too, like Defender, Hummingbird or Pro Sites (I tried updating the theme to the latest version, but the issue is still there).
