Register's signup button results in broken page.

If you click on that button, you get a mostly empty white page with the following html visible on page:

<META HTTP-EQUIV="Refresh" CONTENT="0;URL="><h1><a href="" />VIEW TEMPORARY SITE</h1>

Secondly, why do we have more than one action button on the join membership section of registration? Its pretty confusing. One of them goes to this broken page for me. The other seems to go to my payment gateway. Shouldn't there be only one that goes to the payment gateway or am I missing something?
