OK fixed!

Buddypress was no longer network activated. (The Manage Signups page was still there.) After the WordPress 4.0.1 upgrade I experienced problems on my multisite. Deactivating Buddypress helped (although the problem may have originated elsewhere).

Network activating Buddypress fixes the Manage Signups page. Now I just need to work out the fastest way to deactivate it on 100 blogs!

Thanks Shane – Buddypress Tools was under Tools as you said, on the dashboard of my main blog. I checked all the boxes and ran it but unfortunately it doesn’t fix the permissions problem 🙁

Thanks for your reply.

My main blog’s permalinks are set to Post Name.

The BP component pages exist.

I think r.php is part of the Facebook plugin. I’ve deleted it – wasn’t working anyway.

Can’t find the BP repair tool anywhere. Is it part of the Buddypress plugin, or an add-on?

Sorry, that didn’t make sense 🙂 The problem wasn’t the divs. It was that the button function outputs straight to the screen, rather than into a variable. Problem solved!

Fixed it by putting this in my theme’s function.php:

function add_friend_button() {
     global $members_template;
 
    if ( !isset( $members_template->member->is_friend ) || null === $members_template->member->is_friend )
         $friend_status = 'not_friends';
     else
         $friend_status = ( 0 == $members_template->member->is_friend ) ? 'pending' : 'is_friend';
 
     return bp_get_add_friend_button( $members_template->member->id, $friend_status );
 }

And then called it from my modified template:
$html.= add_friend_button();
