Create New Listing forces user to re-login – stuck in loop

Hi there
I have just changed my DirectoryPress setup to have users register before posting a listings (previously they registered during the listing process).
Page is here: https://horsetalk.co.nz/directory

However now, when they have registered and click on “Create New Listing”, the system redirects them back to a login page:
https://horsetalk.co.nz/directory/wp-login.php?redirect_to=%2Fdirectory%2Fsubmit%2F

re-logging in (despite being logged in already) does nothing – you can get to the My Account area, but when you want to “Create New Listing”, you can’t do it.

The new listings are free.

thanks for any insight …

ps tried to load this under
Home › Forums › Version 7 Themes › DirectoryPress ›

But Directory press was not an option in the dropdowns under Version 7 themes.
