Redirect to 404 when user is not logged in and adding a listing

Hello,

I am experiencing an issue where when the user is not logged in they are redirected to a 404 instead of a login page, when the user is logged in the add listing page shows fine, I have supplied my sites credentials is a previous topic in a private reply for you to review.

Also to note when the redirect is manually removed from the url bar it goes to the login / sign up page as it should

Thank you for your assistance.
