Hello, when I post new article with Windows Live Writer, it showed an error: Invalid Server Response - The response to the blogger.getUsersBlogs method received from the weblog server was invalid.
Then I disabled all the plugins in my Wordpress installation and try. It works. So I active the plugin one by one. And confirm that only "Dagon Design Sitemap Generator" can not be active or the error shows.
Could you modify it?
Here is the article I searched at google, it helps me to solve the problem. You may read it.
