I've created both private and public communities and several members accounts in our staging installation of our website with the Communities WP plugin. Upon joining a community I receive a message that I successfully joined but then cannot see the joined community in my list of communities in the dashboard. I've tried it for both private and public communities (i.e. with and without codes).
I also have Membership WP plugin installed. Could there be some sort of protected content conflict going on here? Any other suggestions?
