I have searched the forum for a solution to this and read through http://en.forums.wordpress.com/topic.php?id=21616&replies=5, but I can't seem to resolve this issue. The topic is now closed and it doesn't give a solution or say if it's for hosted (free) vs. non-hosted blogs.
I host my own WordPress blogs and when I use Windows Live Writer to post using XP, I get this message:
An unexpected error has occurred while attempting to log in:
Invalid server response - the response to the blogger.getUsersblogs method received from the weblog server was invalid:
Invalid response document returned from XmlRpc server
When I post using Vista from my laptop, it goes through, but it doesn't post. When I go into the dashboard, there was nothing I could do to get it to go live. I had to delete the post and recreate it.
I have also tried uninstalling WLW and reinstalling it without success.
Is there a solution to this somewhere that I'm missing?
