Live Writer XMLRPC Error

Have you tried disabling all plugins and using the default theme to eliminate your theme and plugins as a possible source of the problem?

What’s the URL of your blog? Windows Live Writer also has an error log, is there any additional information there?

That did it. Thanks! I didn’t realize about the WLW log. I have found the culprit: NextGEN Gallery.

This is what I found:

The last plugin that I added was NextGEN. The ‘searchgallerytags’ clued me in that it might be it. I disabled it: error gone. Reactivated it: error back.

This is a NextGEN bug, it would appear.

Looks that way. It’s causing PHP warning/errors that are getting included with the XML-RPC responses, messing them up in the process. Make sure you provide that feedback to the plugin author so that it can get fixed.

Hi,

I have a kind of similar problem. I recieve the same error as the topic starter and tried to fix it using the following. Methods

I added this code

if (phpversion()==”5.2.2″) $GLOBALS[‘HTTP_RAW_POST_DATA’] =
file_get_contents(“php://input”);

Source: https://foliovision.com/2007/05/19/xml-rpc-server-wordpress-error/
After that i got a 500 error

$HTTP_RAW_POST_DATA = file_get_contents(“php://input”);

Source: https://josephsmarr.com/2007/06/06/wordpress-xml-rpc-server-accepts-post-requests-only/

Here i also get the same error.
I kind of have no idea how to fix it so does anyone have any idea?

Below is my log output:

I think the most important part is

XML-RPC server accepts POST requests only.”,””

A few days ago i also had some strange accounts in my wordpress admin panel. They had no roles so i deleted the accounts. But i kind of suspect that some one was possibly hacking it.

Anyway does anyone have any idea’s what it might be? Otherwise i`m considering reinstalling wordpress.
