WHEN does the integer output of get_user_count() turns into an array ?
The function get_user_count() in ms-functions.php returns an integer (it calls get_site_option('user_count')
The function wp_version_check() in update.php stores this integer in $user_count on line 55
Directly after that on line 73 it calls this integer with $user_count['total_users']
reason for asking
On my network admin pages I get the error:
Warning: Illegal string offset 'total_users' in /opt/htdocs/html/wp-includes/update.php on line 75
So I need to understand where I need to look (probably something I did somewhere)
