Domain Mapping plugin not saving

I need help with my multisite domain mapping. For some reason, Domain Mapping plugin is not saving the domain where i want the sub site to map to, it just refresh and do nothing. I also checked the database and i don't see any prefix_domain_mapping table there.

define('SUNRISE', 'on'); is placed in wp-config, sunrise.php is moved to /wp-content and DNS of domain name that i want to use is are properly configured.

What im using:
WP Version: 4.1.1
Domain Mapping plugin: 4.3.0.4
Multidomain plugin: 1.3.4.3

Any help is appreciated. Thanks.
