Since installing Domain Mapping, I'm having two problems which are likely related.
1) The new domains are asking me for username and password with a dialog box from the browser (e.g., caused by htaccess restriction (says "Restricted Area")
2) superadmins cannot log into the wordpress admin for individual sites. (wordpress security).
I have already checked htaccess at:
/var/www/ (there's no user security here)
/var/www/wp-admin/ (there's no htaccess here)
I don't see anywhere else that this htaccess security may be. What did I miss?
I do see a .htpasswd at /etc/apache2/ but when I remove that, it causes more issues.
I could really use a more easy to understand step by step on how to install Domain Mapping and Multi-user WP 4.1 .... on a completely fresh setup.
