Hi Wayne,Which version of WP and AWPCP are you using?
You need to have registration turned on for users to be able to edit their ads directly on your site. That should be under Classifieds > Settings > Registration tab. You need to check 'Place Ad requires user registration'. In that manner, users are able to edit the ads directly upon hitting on the Edit Ad menu.
This is what I am using - Thanks.
