404 while trying to view form

I just installed your plugin. I imported an existing google form into the field “The full URL to the published Google Form”. I was able to preview the form and it looked fine, so I published the form. Now, I receive a 404 page when simply trying to view the form.

Any ideas what could be wrong?
