Does anyone know....I am working with a client on his new website and tried to upload to BC. I know that Adobe are shutting it all down - IN TWO YEARS, but it wont let me upload a test site so I can continue working on it with client feedback, for just a few weeks, probably.
I´m afraid, as long as you don`t have some "older" testsites to republsh your "new" site you´ll have to either use a subfolder on your domain/ftp or do the same on your clients ftp with a subfolder.
The address to upload and view would be www.yourdomain.com/newsite-as-test
Muse can handle subfolders for you and even can create one, if needed.
