Manual Install of Multisite Content Copier is not working

When clicking on 'Manual Install' after clicking the 'Install' button for Multisite Content Copier nothing happens. A # is added to the url and the page behind the modal dialog bounces to the top of the page. I'm not able to do one-click install because I use a .ssh key for ftp.

I'm using Chrome 37.0.2062.94 on a Mac.

Thank you.
