Link not working

The checkout page loads using the [woocommerce_checkout], how ever, the checkbox shows and the link for the second set of terms is also present and if you highlight it, it does show the correct link to the page with the terms, however, if you click the link, it does NOT open that page in a new window, but instead a horizontal box appear about the checkbox line, and is completely bank. This appears to be a problem somewhere in the code, either due to the age of the theme being used or something else. This isite is still using the old Enfold Theme. Can someone please advise why this isn’t working? This is vital we get this extra check working ASAP.
