Add Listing link redirects to home page

Hello,

I am using GD to develop a client listing and review site: http://clientstarsystem.org/

I had the site almost ready to go, but wasn’t happy with the default “Places” category, as it doesn’t make sense to front end users. I added the GD custom post addon, and created Clients as a custom post type.

I’ve configured a new Add Listing form, but when I try to navigate to the Add Listing page/form, I get redirected to the website homepage (it worked fine before!). I have looked at, and tried different settings on the Design–>Navigation settings, but nothing I try seems to work.

I would be happy to provide you with a login if you need to look at the settings for yourself.
