White Popup window

Hi there,

I have installed the plugin and included it on a page with the Divi module (Google Drive Gallery). The connection to the Google account has worked and it shows me the right folders. After clicking on “Configure” I can select the folders I need, but as soon as I click on Filter, Advanced, Notifications and Permissions, the popup window turns white and I can’t select anything. Any ideas what could be the reason for this? Thanks!
