I am having issues that I think is caused by the Pro Site plugin

My domains that are pointing to my multisite resolved at https://nigelweb.com/pro/ instead of https://nigelweb.com

Please see http://www.mymattapancdc.org which is the latest domain I pointed. I had to un-mapped it because of the error with the redirect. I checked with the host and everything on their end is good.

The site ID is 20 in the multisite

For the longest time I have been requesting help with my site because I cannot properly log into all the clients site backend. I get an ssl warning. It keeps wanting to use SSL for the clients backend. Can someone please check it for me.
