Try this workaround: hover over the eye with your mouse, right click and then copy the link location. Open a new tab, then paste the link in.
It should look something like:
http://yourmoodlesite.com/admin/auth.php?sesskey=1234567890ABCDEF&action=enable&auth=email
That should enable it.
Then you can go down to Common settings and you will be able to choose Email based self-registration from the pulldown menu. (You have to enable the method first before the pull down knows what options to allow you to enable.)
