Success message error

Upon completing the registration form (page linked) the completion message and all other elements on the page change to a strange orientation and make the page look ugly. How can i get the success message to appear under the title in the same section.

Ps. If you make an account to try out the response, please use name and username: TEST (so i know which accounts to delete later)

Thanks.
