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?
There is probably a plugin that is causing invalid XML to be included in the response. I recall a few people mentioning this in connection with the Google Sitemaps plugin. Try disabling your plugins one at a time and see if that solves the problem.
