Domain mapping plugin database

Hi,

I was changing settings of HTTPS/HTTP and the site crashed. I couldn’t login in to Admin area. What I did was,

Server side :

1. Remove code from wp-config.php

2. Deleted domain-mapping plugin from plugins folder

3. Removed sunrise.php from wp-contents folder

Now I can login into my admin area. When again installed domain mapping plugin, it is using the same settings of previous one and crashes.

How do I remove all the settings of this plugin from database? Please help me to remove it completely and I wanted to install this plugin newly without old settings.

Help please.
