masjmh on "[Plugin: WordPress MU Domain Mapping] After Adding Sunrise in wp config - getting error"

Hi All,

I want to create multisite wp. I have installed this Plugin and try to configure wordpress as mention in the tutorial of this plugin. I get error message if I add define ('SUNRISE', 'on'); in my wp config file.
I get following error message:
Error establishing a database connection.
I have installed wordpress in xamppp.
Thanks
