URGENT: Both the subdomain and the mapped domain are showing

Hi There,

We are in trouble: When we activate Pro Sites on our network, both the subdomain and the mapped domain of all sub-sites are showing. (Like discussed here: https://premium.wpmudev.org/forums/topic/subdomain-redirected-to-domaincom#post-1176463)

But when we deactivate Pro Sites HTTPS doesn't work anymore on the front end. At the backend it still works.

We don't really need Pro Sites anymore as we changed our business model. BUT we need SSL. So please help us deactivating and removing Pro Sites so that HTTPS will work again.

What can we do?

Thanks, T.
