BuddyPress.org

1st:

As yesterday mentioned, my startpage:

http://1a-spielwiese.de

and the subdomains:

http://balletttaenzerinnenkrzbg36.1a-spielwiese.de/

http://kampfsportlerinnenneuwied.1a-spielwiese.de/

work, and I can login into the different dashboards (entire network, 1a-spielwiese.de, subdomains).

2nd:

But it seems, all this gives me no access to the social network function of BuddyPress:

a) E.g., wenn I (using my superadmin-profile) try to do something with the BuddyPress-toolbar, e.g. sending a message, I become redirected to the login form:

Between the WordPress-Logo and the two form fields (user name and password) is written:

“Bitte melde dich nochmal an.
Du musst Dich anmelden, um Zugriff zur angeforderten Seite zu bekommen.”

(Please login again.
You have to be logged in, for accessing the page at issue.)

Within my browser adress line appears:

http://1a-spielwiese.de/wp-login.php?redirect_to=http%3A%2F%2F1a-spielwiese.de%2Fmembers%2Fs-admin-1a%2Fmessages%2Finbox%2F&action=bpnoaccess

b) The admins of the indiviual blogs can login to their own blogs, but not not the start page of entire network.

c) As well there are buttons for making friendship nearby the avatars respec. user names.

As well there is no opportunity to post something into the activity stream.

What could be the cause of the misfunctions and how can I resolve the problem(s)?
