Uninstalling Domain mapper

Hi

Was having a few issues with Domain mapper plugin and would like to uninstall it so I can check whether it was a host problem or set up problem

I have removed the Sunrise .php file
I have removed the sunrise code from wp-config.php
Also removed the domain-mapping.php form mu-plugins

But I can still see the Domain Mapping option in the settings Menu of the Network admin pages

Ay help pleas

regards

John
