Directory Version 1.0.7 Sign Up Button Problem!

Hi, the ‘sign up’ button below the search box goes to the checkout page,.. quote ‘Sorry, we can’t find the content you’re looking for at this URL. Please try selecting a menu item from above or to the side of this message to get where you’d like to go’.

Also I’m set up for paypal express, but during sign up the option to pay be credit/debit card comes up also, will that still take my customer to paypal checkout?

Thanks for your help?
