After installing the Spirit form, I noticed that the sign up page is much different from the rest of the site. The theme somehow is not applied to the sign up page and the wp-signup.php page looks drastically different from the rest of the site. Basically the page is white with a bunch of text. You can't even seen the form fields or were you're supposed to input text. Is there any way to edit the sign-up page through upfront? Is there any way to edit the wp-signup.php page at all through other means?
