Register does not redirect after subission

When i test a registration form on the site and submit, nothing happens. I can see on the back end that the account is pending/created but on the front end it does not redirect to a new page.

Also, how do I adjust the css so there is an extra space below the form? On tablets a menu is crunching up against the bottom of the form...

PS I granted support access to the site if you need to look at it
