After installing the new latest version, the data import doesn't work. Like many others I get "Failed to import XML file" error. I tried to make the changes that were suggested in other similar posts here (like changing FS permissions) but nothing seemed to fix it. I'm quite stuck with this one right now.
In a post dating a week back it was mentioned that the themes were updated to resolve this problem, but it still happens even with a fresh download of the them from yesterday.
