#5834: Notice while activating a member (with no role on any blogs) on a multisite
config

     Type:  defect (bug)  |     Status:  new
 Priority:  normal        |  Milestone:  2.1
Component:  Blogs         |    Version:
 Severity:  normal        |   Keywords:  has-patch
--------------------------+-----------------------
 Multisite config with users & blogs registration opened

 Steps to reproduce :
 - register a dummy account by making sure you don't request a blog
 - with a super admin account, go to the Manage Signups screen and activate
 the member.

 Notice error in {{{bp_blogs_add_user_to_blog()}}} using {{{array_keys()}}}
 at line 862. I think as the member has no role on any blogs the check for
 the user meta {{{$wpdb->get_blog_prefix( $blog_id ). 'capabilities'}}}
 simply returns an empty string.

 Casting this to an array is fixing the issue, see attached patch.
