Edit Listing Not Working For Non Admins

I am not able to edit any listing in the directory plugin unless I am logged in as admin. When I click the "Edit" link the page refreshes and nothing happens.

I have ran a plugin conflict and non of my plugins seem to be causing the issue. I have this thread* open and we have made some core updates to the plugin files as you can see from this thread.

*when clicking edit the page no longer goes to a white page.

Can someone please help. Support access is granted. My launch date for this project is April 1 and more and more bugs keep compounding every time we get one fixed it creates another two!

Thanks,
William
