Today I tried an import from my Dreamhost  version of WordPress 3.3.2 using the "Import Blogger" tool. This time it failed; Google rejected the authentication request with a cryptic message:
The page you have requested cannot be displayed. Another site was requesting access to your Google Account, but sent a malformed request. Please contact the site that you were trying to use when you received this message to inform them of the error. A detailed error message follows:
The site "http://kateva.org" has not been registered.
I couldn't fine any fix for this, though I did come across many reports of the error with various half-fixes. I wonder if this is because both my Blogger blog and the WordPress blog are on kateva.org. Or perhaps this is another sign that WordPress is problematic; I think if I do move to WordPress I will pay for WordPress.com and the associated support.
 If you use the promo code of KATEVA you get $50 off the 1st year fee and I get an equal credit (50/50 split).
