There was a time when Facebook allowed you to create a Business Page without having a Personal Page, but that's no longer true. If you've received a message that says "Name can't be blank," it's because our system can't find a Personal Page associated with your Business Page. Solving this error is as easy as creating a Personal Page to go along with your Business Page.
Once you've created your Personal Page, please try linking your account again in VerticalResponse. And don't worry, we won't post anything to your personal page unless you tell us that's what you want.
