Hi Kim,
Thank you for the feedback. It should be okay with any theme out there, including Divi, as usually high quality themes follow the WordPress development guidelines. I’m almost positive it should still work, unless Divi does some weird stuff (which I doubt). It could be a conflict with something else as well, but I can’t tell without going through the code directly. If you want, I can take a direct look at the code and debug it. For that please add temporary FTP access.
