When a sub-user clicks "New Post" on the Admin toolbar, the link shows/reads as http://mainsite.com/wp-admin/post-new.php, instead of
http://mainsite.com/subsite/wp-admin/post-new.php. when clicked a WordPress message error comes up, which states you do not currently have privileges on this site, etc....
Second error, which is possibly related. when I login as the Super admin and goto My sites. All the subsites are shown.
The sites with the domain mapped show the mapped-domain.com/wp-admin, which is how it should work but the non mapped domains show mainsite.com/wp-admin on the dashboard links instead of mainsite.com/subsite/wp-admin?
