Embeds and popouts are no longer working

I’m on the latest version of the plugin.

I don’t know when this problem started, but my Drivr Lite-embedded Google Docs simply show a big gray blank area instead of the embedded document. If I then click the Pop-out icon, a new browser tab opens with a Google docs url but the page only shows the Google docs navbar at the top and the rest of the page is blank. At the top, I can click ‘Open with Google Docs’ and only at that point can I see the correct document in Google Docs.

any suggestions?
