Costumizer keeps loading when this plugin is active

Hi, When I install this plugin, the costumizer keeps loading and becomes unusable. When i disable this plugin, all works fine. It has not been updated for 4 months, so I wonder if this plugin will get new updates soon, so it does not make the costumizer unusable? Thanks! Annie Maybe this info can be useful: I deactivated all other plugins, cleared all cache, to test if the issue was gone. It was not. I also tested in a basic WordPress set-up, and first it seemed to work there, until I switched to another form to edit. After that, it kept loading and loading, just like in the other website. Costumizer comes up again, as soon as I deactivate this plugin. There is also a warning that this plugin was not tested with my, most recent WordPress version. Thanks, Annie We have released an all new interface for styling the forms. The plugin is no longer dependent upon customizer.
