Same problem, could you fix this quickly?

Oh stupid me! I did not add the subdomain into the configuration in the server. SO now it is working fine, sorry for my foolishness!

I had to also remove the hole plugin (installer) to get the admin working properly. I hope this lasts now.

Jei, Wasca, thank you!! I have been struggling with this problem for hours and that really helped, now the admin is as it was! Great, saved me hours of work!

Wow, I got it working!

I had installed domain mapping, but I remowed it and then made the following records to the DNS Zone:
https://www.newsubdomain

and it started to work!!! How happy I am, I have been fighting with this for 2 days now.
