I want to use the quick themes...the horse one and it will not allow me.... it keeps making me sign in. I was able to use these themes before. Please tell me what i am doing wrong. Thank you!!!

I am having exactly the same problem and have been trying repeatedly for about 5 hours now. I've rebooted my machine but still not working. Maybe it will be back to normal by tommorrow.

I still have the same problem, I made a custom template, now it wouldn't let me do that either.

I found this out a few minutes ago.
Go into mAnage HOstage
then website wizard
and then go to step by step.

nothing will change, just you can change your theme
