Windows Live Writer and WordPress Error – Invalid response document returned from XmlRcp Server….SOLUTION

Today, I upgraded to WordPress 2.5.1, which I am glad to say was really simple.  Along with this, one of my colleagues suggested I try Windows Live Writer as a blogging tool to post to this blog, so I installed it.

When you first open Windows Live Writer it has to query your blog via the xmlrpc.php file in the WordPress root directory.  However, when I tried this I kept receiving the following error;

“Invalid response document returned from the XmlRcp sever”

After a bit of digging around the WordPress files and folders, here is how I fixed it;

1. Open your favourite text editor (I like Notepad++ because it also shows me characters that some editors can hide).

2. Open the following four files and check for extra characters after the closing PHP tag (which looks like “?>”).  If you find ANY blank spaces or blank lines after this closing tag, delete them.

• wp-blog-header.php
• wp-config.php
• wp-settings.php
• xmlrcp.php

3. Save your files and upload them to your server.

4. Try Windows Live Writer again and hopefully enjoy using it
