I have spoken to Ron about this a couple of times on the Studiopress forums and he has since told me to post it here too. The plugin used to work but at some stage as a result of updating WP, BP and the Genesis Serenity theme I am using, the plugin stopped longer works. I didn't realise straightaway so obviously it is difficult to know what might have caused it.
The site operates as a business directory so it really is almost useless when people can not click into the members profile to find out more about them and contact them.
I would really appreciate if you can tell me how to get the plugin working again.
