is it possible to create a multisite with ultimate facebook?

Hey there :slight_smile:

I wonder if it is possible to create a multisite while registering with the Ultimate Facebook Plugin. I can only see "Login with Facebook" (find image below) instead of "Register with Facebook" on my Signup-Page.

I also switched back to a WP-default theme and tried to do it - with no success.
Still remains as "Login with Facebook".

Best wishes,
David
