We supposed till now that the error message “Server error -32700 occurred" shows that the Windows Live Writer tried to publish on a corrupted Wordpress installation.

But there is another less dangerous possibility, a wrong character set. If you blog is set for example to UTF-8 and the Windows Live Writer tries to publish with ISO-8859-2 you will get the following error message:

“an unexpected error has occured while attempting to log in: Blog Server Error -32700 Occured parse error. not well formed”

How do you change the character set?

Windows Live Writer auf Tools >> Accounts

Edit >> Advanced

Done.
