 * Have you tried:
    – deactivating ALL plugins temporarily to see if this resolves
   the problem. If this works, re-activate them individually (one-by-one) to find
   the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating
   via [FTP or SFTP ](http://codex.wordpress.org/FTP_Clients)or whatever file management
   application your host provides. Also remember to deactivate any plugins in the
   mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old.–
   switching to the unedited default, core-bundled Theme (such as Twenty Fourteen)
   for a moment using the WP dashboard to rule out any theme-specific issue. If 
   you don’t have access to your admin area, you can switch to the default theme
   by renaming your current theme’s folder in wp-content/themes and adding “-old”
   to the end of the folder name using via FTP or SFTP or whatever file management
   application your host provides. Alternately, you can remove other themes except
   the default theme. That will force your site to use it. – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems (because the hooks remain unless plugins completely removed or some 
   plugins stick around in cached files. So by renaming the folder, you break them
   and force them inactive). – **MANUALLY** re-uploading all files and folders EXCEPT
   the wp-config.php file and the /wp-content/ directory from a fresh download of
   WordPress. Make sure that you delete the old copies of files & folder before 
   uploading the new ones. Read the [Manual Update ](http://codex.wordpress.org/Updating_WordPress#Manual_Update)
   directions first! – running the upgrade manually via wp-admin/upgrade.php – **
   BTW, if you haven’t already done, always backup everything (including your database)
   before doing any actions, just in case something really goes wrong. It’s a great
   safety net.**

 * Hello,
 * I am seeing errors on my server as so:
 * body.xml:1: parser error : ParsePI: PI xmlversion space expected
 * I’m seeing, sometimes, up to 20 errors per hour, sometimes none, in my server
   logs. I have recently started to upgrade my 70+ WordPress sites to WP 3.9.1, 
   and have upgraded three sites as of now. Prior to this, I wasn’t getting any 
   errors like this. Maybe this has something to do with this?

 * I have an identical problem and have had it now since January. Any body found
   a fix or isolated the problem?

 * Hello,
 * The issue is that your site or server is under an XML-RPC attack. If you are 
   able to view the Apache status of the server, you would see that there are attempts
   to POST to the xmlrpc.php file in your site’s WordPress directory.
 * Try installing the Disable XML-RPC plugin or, better yet, install the iTheme 
   Security plugin for a better overall response to security threats.
 * Peter

 * Thank you Peter, much appreciated.
 * I had just concluded the same thing although not how to fix it. I am fairly sure
   that all my sites are secure against Pingbacks but I will try the Disable plugin
   and see if that makes a difference to the error turning up in the logs.
