I am setting up a network (sub-domains) using the Blogs-MU

Hi,

I am setting up a network (sub-domains) using the Blogs-MU theme on my primary site. I have both buddypress and bbpress installed and network enabled (in that order). I have enabled both sites and user accounts to be registered.

When I am logged out and go to (insidehealthyliving.com/register/), I see the fields to create an account, and have the choice to create a new site, but there is no "Submit" button and I have the following error:

Fatal error: Call to undefined function bp_blogs_subdomain_base() in /home/ihladmin/public_html/wp-content/themes/blogs-mu/registration/register.php on line 193

I have checked line 193 of ...blogs-mu/registration/register.php and it is blank.

Any suggestions?

Thanks!
Mark
