Domain Mapping / Single Sign-On Error

Tried enabling your domain mapping plugin after some previous errors.

For some reason, when I activate it, it attempts to convert my site to SSL and errors happen...

Not sure what I have set up wrong here... But I'd like to enable that so the other plugins work more smoothly... Currently single sign on is not working either, which I think is controlled by that plugin as well. I have to re-login each site in the network.

Support access is already enabled...
