I have installed WMPU on tbreak.me
I have created a few blogs like tech.tbreak.me and souq.tbreak.me that are using the Domain Mapping Plugin and set to tech.tbreak.com and souq.tbreak.com
The problem is that none of the users can login if I have the domain mapping set. If there is no domain mapping, the user can login at tech.tbreak.me but as soon as the mapping is set, it simply doesnt work.
As suggested by someone in the forums, I have also commented the four lines in wp-config.php
// define('DOMAIN_CURRENT_SITE', 'tbreak.me' );
// define('PATH_CURRENT_SITE', '/' );
// define('SITE_ID_CURRENT_SITE', 1);
// define('BLOGID_CURRENT_SITE', '1' );
