Widows Live Writer Error “Invalid response document returned from XmlRpc server” After WordPress Update Fix

My solution for the Windows Live Writer (WLW) error:

The response to the metaWeblog.newPost method received from the blog server was invalid:  Invalid response document returned from XmlRpc server

Warning: This solution entails editing a WordPress core file and is therefore generally not recommended. If some PHP guru knows how to fix this with code in the functions.php file or something, I’m all ears!

  1. Find class-wp-xmlrpc-server.php in wp-includes folder
  2. In the code, locate the line “if ( strpos( $post_content, $file->guid ) !== false )”
  3. Directly before it add another line of code…
if($file->guid && !($file->guid == NULL))

I’m usually not big on editing core files, but I use WLW to blog daily and this error keeps cropping up. It’s highly frustrating and there are numerous fixes around the web that are both more time consuming and not necessarily effective. This is a quick, down-and-dirty fix that will get you up and running.

Solving FTP Deletion Error “550 Prohibited file name”

Trying to delete a file via FTP and unable to? Getting a “550 Prohibited file name” error? Annoying! But also very easy to fix. Create a php file called “unlink.php” with this code, replacing the “YOUR-FILENAME-HERE” with–what else?–your undeleteable file name. 

<?php unlink('YOUR-FILENAME-HERE');?>

Upload it to the directory with the file in question, and visit the script in your web browser. It will remove the previously unruly file. ((Thanks to irasmith’s forum post for this solution.))

PHP noobs, please remember to have NO blank spaces before or after the beginning of your code in PHP files, or you’re liable to get a “Cannot modify header information/Headers already sent” error. You can create the file in a text program and simply rename it with a .php extension.
