@a_5mith I have it setup on a new DO droplet using the server IP (no domain yet) for both server_name and the base_url - basically replacing localhost referenced in my previous post. Hope that makes sense.
Thanks will give this a try.
Also considering having the WP site in an iframe on my NBB homepage, then styling both to match. However, with this option, I'm not sure how best to setup SSO. Is there a way to use NBB as Login, Registration and Profile and pass the info to WP. ie using NBB as the AUTH provider?
