The Domain Mapping plugin is not redirecting to dashboard after the last plugin update, I did move sunrise.php file but still not redirecting but only when I disable Domain Mapping plugin I can access the dashboard.
It shows "many redirects error" on FireFox.
After domain mapping, this problem is often seen with various users facing redirect loop error. In my opinion you should assure first that no problem is there in your web server and sub domain is pointing to the right place. You should try remote login or use domain mapping page once. If problem still remains, you need help of any expert domain name troubleshooting for example http://www.domainia.com/. about 2 years ago
