What have I missed in the upgrade from v3.7 to Parker, please? I have spent a while looking over the updated site and am really happy, and upgraded both my main site and a networked site that runs under that one… but now I find that I cannot create a new networked site.
I fill out the little form, with the name I need. I create a new e-mail and account, and so on. It looks like it works, but clicking on the link doesn't bring up Another WordPress site… it brings up the White Screen of Disappointment.
