I have tried to install the domain mapping plugin in this site for use with multisite..
the site is http://cg-o.com and the multi site I'm trying to have mapped is http://cg-o.com/choosegrowthbook/
I want the domain http://choosegrowthbook.com to be mapped to the http://cg-o.com/choosegrowthbook/
I have created an A record on godaddy pointing to 50.22.10.73
Hope that makes sense... Let me know if you need any other info from me!!
