Issues Using Divi Builder

I have an existing Divi website that the members would like to include a business directory for themselves. After checking off the server requirements and installing GeoDirectory, everything is fine until I try to change the generated pages into a Divi layout. I’m using the classic editor in the backend as your support documents suggest. I have deleted all of the setup text code prior to clicking the “Use Divi Builder” button. But as soon as that button is clicked, nothing can be edited. The page will not return to the standard editor either. I have to disable the GeoDirectory plugin to get the page to be editable again. I’ve even tried the front end visual builder [code module], but it really gets messed up then. Plus the page cannot return to the backend to edit other page settings. The builder just spins and spins (until I disable the GeoDirectory plugin). I've tried disabling other plugins to eliminate any possible conflict, but no luck. Any suggestions? I really wanted to use this plugin, but find it impossible to work this way.
