Fails on multisite registration

Hi,

I just tried to set up reCaptcha for my multisite registration. Seemed easy to set up and getting from the first form (user/email) to the second (site name/title) worked fine. But when sending the second form, that form just reloads. I cannot get to the confirmation page. Disabling the plugin, it works fine.

Thanks for the plugin and your support!
