I have three fully hosted domains with one of them having WPress installed.
I tried yo install WP on the other two last Sunday morning and I got this message:
"We're currently migrating your data to a new-and-improved version of our one-click software installer. If any of your previously-installed software is not appearing on this page, please give it 24 hours and everything will be groovy!"
I continue to get this message after three days.
